<p>Solve for x : z/6 + 4 = 7
x= 18</p>
<p>What do you need an explanation for? And I think you ment to put X instead of Z</p>
<p>But anyways. Get the 4 to the other side by subtracting it so you get x/6=3 then multiply both sides by 6 to get rid of the division so then x= 3(6) or 18</p>
<p>(x/6) + 4 = 7
(x/6) = 7 - 4
(x/6) = 3
(x/6) * 6 = 3 * 6
x = 18</p>
