-2x + 4x + 20 = 2 - 16x - 12
2x + 20 = -16x - 10
18x = -30
x = -30/18 = -15/9

First, multiply 3 by (2x - 7), which gives us 6x - 21. That makes the equation 4x + 6x - 21 = 19 Get all the numbers on one side, and the variables on the other (so add 21 to both sides) 4x + 6x = 40 Simplify the left side: 10x = 40 So, x = 4

-2x + 4x + 20 = 2 - 16x - 12
18x = - 30
x = - 30 / 18 = - 5 / 3

-2x+4(x+5)=2-4(4x+3)
-2x+4x+20=2-16x-12
18x=-30
x=-5/3.

its -5/3
use distribution method, combine like terms, divide both sides, and you get x=-5/3
