Which algebraic expression is equivalent to the expression below?

(3x + 12) + 8x

a-5x + 12
b23x
c15x + 8
d11x + 12

Answer 1

3x + 12 + 8x --- parenthesis are not needed....combine like terms
so what is 8x + 3x ??

Answer 2

what is 8 + 3 ?

Answer 3

11

Answer 4

the x's do not change when adding...so 8x + 3x = 11x.
and even though 12 has no like terms, you cannot forget about it. And you cannot add/subtract unlike terms.
So we end up with : 11x + 12

understand ?
