Question

2 x + 4 x - 3 + 8 x + 18 = 43

whats x

Answer 1

Answer:

2x+4x-3+8x+18=43

We move all terms to the left:

2x+4x-3+8x+18-(43)=0

We add all the numbers together, and all the variables

14x-28=0

We move all terms containing x to the left, all other terms to the right

14x=28

x=28/14

x=2

(hope that helps)
