Today we are going to take a look at solving two-step equations.<\/p>\n<p>Let&#8217;s start with an example:<\/p>\n<h2><span id=\"Example_1\" class=\"m-toc-anchor\"><\/span>Example 1<\/h2>\n<div class=\"examplesentence\">\\(3x-4=11\\)<\/div>\n<p>\n&nbsp;<br \/>\nTo solve, we need to find the value of \\(x\\) that makes this statement true. We do this by getting \\(x\\) by itself on one side of the equation.<\/p>\n<p>When solving two-step equations, always undo the addition or subtraction first and then undo the multiplication or division.<\/p>\n<p>So, for this problem, we&#8217;re going to start by undoing the subtraction by adding 4 to both sides.<\/p>\n<div class=\"examplesentence\">\\(3x-4+4=11+4\\)<\/div>\n<p>\n&nbsp;<br \/>\nThat means these cancel out, and we&#8217;re left with \\(3x\\) on the left side, and \\(11+4=15\\).<\/p>\n<div class=\"examplesentence\">\\(3x=15\\)<\/div>\n<p>\n&nbsp;<br \/>\nThen, we undo the 3 being multiplied by \\(x\\) by dividing both sides by 3. Remember, any time a number is next to a letter, it means they are being multiplied. So this shows us multiplication. So, to undo that, we simply divide both sides by 3.<\/p>\n<div class=\"examplesentence\">\\(\\dfrac{3x}{3}=\\dfrac{15}{3}\\)<\/div>\n<p>\n&nbsp;<br \/>\nOur 3s cancel out and we&#8217;re left with \\(x\\) on the left side, and \\(15\\div 3=5\\).<\/p>\n<div class=\"examplesentence\">\\(x=5\\)<\/div>\n<p>\n&nbsp;<br \/>\nAnd that\u2019s our answer! We can check it by plugging it back into our original equation and seeing if it is a true statement. So let&#8217;s do that.<\/p>\n<div class=\"examplesentence\">\\(3(5)-4=11\\)<br \/>\n\\(15-4=11\\)<br \/>\n\\(11=11\\)<\/div>\n<p>\n&nbsp;<br \/>\n\\(11=11\\) is a true statement, so that verifies that \\(x=5\\) is the correct answer.<\/p>\n<h2><span id=\"Example_2\" class=\"m-toc-anchor\"><\/span>Example 2<\/h2>\n<p>\nLet\u2019s take a look at another problem.<\/p>\n<div class=\"examplesentence\">\\(\\dfrac{x}{4}+5=7\\)<\/div>\n<p>\n&nbsp;<br \/>\nRemember, we first want to undo the addition. So, to undo addition by 5, we&#8217;re going to subtract 5 from both sides.<\/p>\n<div class=\"examplesentence\">\\(\\dfrac{x}{4}+5-5=7-5\\)<\/div>\n<p>\n&nbsp;<br \/>\nThat gives us \\(\\frac{x}{4}\\) (or \\(x\\div 4\\)), these (5s) cancel out, remember, and then \\(7-5=2\\).<\/p>\n<div class=\"examplesentence\">\\(\\dfrac{x}{4}=2\\)<\/div>\n<p>\n&nbsp;<br \/>\nSo, now we&#8217;re left with division: \\(x\\) is being divided by 4. So, to undo this, we simply multiply both sides by 4.<\/p>\n<div class=\"examplesentence\">\\(4\\times \\dfrac{x}{4}=24\\)<\/div>\n<p>\n&nbsp;<br \/>\nOur 4s cancel out and we&#8217;re left with \\(x\\) on the left side, and \\(2\\times 4=8\\).<\/p>\n<div class=\"examplesentence\">\\(x=8\\)<\/div>\n<p>\n&nbsp;<br \/>\nSo our answer is \\(x=8\\).<\/p>\n<h2><span id=\"Example_3\" class=\"m-toc-anchor\"><\/span>Example 3<\/h2>\n<p>\nLet&#8217;s do one more example together before we go.<\/p>\n<div class=\"examplesentence\">\\(-3x+20=2\\)<\/div>\n<p>\n&nbsp;<br \/>\nSo, first we&#8217;re going to undo this addition by subtracting 20 from both sides.<\/p>\n<div class=\"examplesentence\">\\(-3x+20-20=2-20\\)<\/div>\n<p>\n&nbsp;<br \/>\nThat leaves us with:<\/p>\n<div class=\"examplesentence\">\\(-3x=-18\\)<\/div>\n<p>\n&nbsp;<br \/>\nAnd then we need to get rid of this \u22123 being multiplied by \\(x\\), so we divide both sides by \u22123. <\/p>\n<div class=\"examplesentence\">\\(\\dfrac{-3x}{-3}=\\dfrac{-18}{-3}\\)<\/div>\n<p>\n&nbsp;<br \/>\nThis leaves us with:<\/p>\n<div class=\"examplesentence\">\\(x=6\\)<\/div>\n<p>\n&nbsp;<br \/>\nSo \\(x=6\\) is our answer.

Subtracting 10 marbles from one-half of the number of marbles that are in the bag gives us the number of marbles that have been counted.
