Question

-2 (y + 3) – 6 (y – 10) = 42

Answer 1

1 Expand.

-2y-6-6y+60=42

2 Simplify -2y-6-6y+60 to -8y+54.

-8y+54=2

3 Subtract 54 from both sides.

-8y=42−54

4 Simplify 42-54 to -12

-8y=-12

5 Divide both sides by -8.

y=-12/-8

6 Two negatives make a positive.

y=12/8

7 Simplify 12/8

y=3/2

or

y=1.5
