Which value of a would make the following statement true? -3(2x + a) = -6x + 15

1 answer:

6 0

Your answer is -5.
This is because, if you expand the single bracket, you get -6x -3a, and since the other side of the equals sign is -6x + 15, then you need to do 15 ÷ -3 = -5.

I hope this helps!

Answer:

$-15$

Step-by-step explanation:

We can factor out a 1 from -3 to get $5\cdot(-3)=5\cdot-1\cdot3=-1(5\cdot3)$ .

We know from simple arithmetic that $5\cdot3=5+5+5=10+5=15$ .

So, our answer is $-1(15)=\boxed{-15}$
