1/6(y+42)-15=(-3)

Question

What does X  equal?

Answer 1

 Assume it is (1/6)(y+42)-15=(-3)

Multiply both sides by 6,

y+42 - 90 = -18

Isolate y,

y = 90-18-42 = 30 <==Answer

Answer 2

1/6(y+42) = -3+15 To change sides, always use equal but opposite signs. 1/6(y+42) = 12 y + 42 = 12 x 6 (opposite of division is multiplication) y+42 = 72 y = 72 - 42 therefore, y =30
