Question

2(3y+6)−3(−4−y)
A 9y
B 5y+24
C 9y-24
D 9y+24

Answer 1

First distribute.

2(3y+6)-3(-4-y) =

6y+12+12+3y =

9y+24

Your answer is D.

Answer 2

C 9y-24 because

2 x 3y = 6y

2 x 6 = 12

so 6y + 12

then

3 x - 4 = - 12

3 x y = 3y

so - 12 + 3y

so like terms

6y + 3y = 9y

and

-12 + 12 = -24

9y - 24
