8(5x-2) = 64 Use distributive property and multiply 8 by everything in the parentheses. 40x-16 = 64 Then add 16 to both sides to eliminate the 16 on the left side, leaving the x by itself. 40x=80 Finally, divide each side by 40. This gives you the final answer. X=2
<span />Step 2: Add 16 to both sides.<span><span><span><span>40x</span>−16</span>+16</span>=<span>64+16</span></span><span><span>40 x</span>=80</span>
<span />Step 3: Divide both sides by 40.<span><span><span><span><span>40x</span>40</span></span></span>=<span><span><span>8040 </span></span></span></span><span>x=<span>2</span></span>
