Question

Please help trying to answer it can be with or without step with step

Answer 1

a) 7x (x is a variable so it does not change)
b) (3a-a)+(4b+2b) = 2a+6b
c) 3bd+(5d+2d)+(-2b-b) = 3bd+7d-3b
d) -2ac-c+(4ab+3ab) = -2ac-c+7ab
e) (6a+8a)+(1+5) = 14a+6
f) (14x+12x)+(6-8) = 26x-2
g) (7b+3b)-(3+2) = 10b-5
h) (3j+8j)-(-4+6) = 11j-2
i) (-4g-6g)-(-5-12) —> (-10g)-(-17) = -10g+17
