Question

How do you solve `5[x - 4(1 - 2x) - 6] - 3(x +10) = 40x - 12`?

Answer 1

x= 9

Explanation:

1) `5[x-4(1-2x)-6]-3(x=10)=40x-12`
2) `5[x-4+8x-6]-3(x=10)=40x-12` Distribute "-4"
3) `5[9x-10]-3(x+10)=40x-12` Simplify
4) `45x-50-3x-30=40x-12` Distribute the "5" and "-3"
5) `42x-30=40x-12` Simplify
6) `2x-30=-12` Subtract 40x to both sides
7) `2x=18`Add 30 to both sides
8) `x=9` Divide both sides by 2
