Question

Which expression will you generate if you combine the like terms in 5x + 6x + y + y + 3y + 4 + 6 + 2?

A.
5(x + y + 7)
B.
5x + y + 2
C.
11x + 5y + 12
D.
x + 8y – 12
E.
2x + 4y – 10

Answer 1

C. 11x + 5y + 12. You add all the terms with x which would be 5x + 6x = 11x. Then you add (1)y+ (1)y + 3y = 5y. Last part should be easy, 4 + 6 + 2 = 12. Combine all of those and you have 11x + 5y + 12.
