Question

What is the value of y, if 3+12(y-4)=40?

Answer 1

3 + 12 (y-4) = 40 *Use distribution* 3 + 12y - 48 = 40 *combine like terms* -45 + 12y = 40 * what you do to one side of the equation you have to do to the other side -45 +12y = 40 +45 +45 ----------------------- 12y = 85 *now you divide to isolate variable* 85 ------- = 7 12 Y =7
