Question

(5y - 1) + (-2y + 4) A) 3y - 5 B) 3y + 3 C) 7y + 3 D) 7y - 3

Answer 1

The answer to this is B. all you do is combine like terms, like 5y minus 2y and negative one plus 4.

Answer 2

(5y - 1) + (-2y + 4) 
= 5y - 1 - 2y + 4
combine like terms

5y - 2y = 3y
-1 + 4 = 3

so (5y - 1) + (-2y + 4)  = 3y + 3

answer
B) 3y + 3
