Question

Which is equivalent to the expression below?

2k + (−3m ) − 6k + 2m
A. −4k + (−2m)
B. −4k + (−m)
C. 4k − 5m
D. 4k − m

Answer 1

−4k + (−m)

Explanation:

combined like term:

solve for k: 2k - 6k = -4k

solve for m: -3m + 2m = -1m which is -m

combined together the equation: -4k + -m or it can just be -4k - m
