Question

8/3(z+11)=y solve for z.

Answer 1

z = (3/8)y - 11

Explanation:

Undo what has been done to z, in reverse order. Here, 11 is added and the sum is multiplied by 8/3.

To undo the multiplication, multiply the equation by the inverse, 3/8:

(3/8)(8/3)(z+11) = (3/8)y

z +11 = (3/8)y . . . . . . . . . simplify

To undo the addition of 11, add the opposite of 11 to the equation.

z +11 -11 = (3/8)y -11

z = (3/8)y -11 . . . . . . . . . simplify
