Question

Which value of a would make the following statement true? 6(2x + a) = 12x + 30

5
-5
4
-4

Answer 1

Again, you need to use the distributive property
12x + 6a = 12x + 30

Answer 2

6a = 30
a = 5

Answer 3

Thanks @KirbyLegs :)

Answer 4

You don't need to use the distributive property..
simply take the gcf of the right side and divide :)
6(2x + a) = 12x + 30
6(2x + a) = 6(2x+5)
divide by 6
2x + a = 2x +5
subtract 2x from both sides.
a = 5

Answer 5

I didn't think about it that way. Thanks @shamil98
