User: 8x + 4 = 4x – 4

Weegy: Sure. I'll change one variable at a time: 8x + 4 = 4x – 4 ; 8x = 4x - 4 - 4; 8x = 4x - 8; 8x - 4x = -8; 4x = -8; x = -8/4; x = -2

User: 4x – 4 + 3x = 3x + 5 – 5x

Weegy: 4x – 4 + 3x = 3x + 5 – 5x ; 7x -4 = 3x + 5 ; 7x = 3x + 5 +4 ; 7x = 3x + 9 ; 7x - 3x = 9; 4x = 9 ; x = 9/4 ; x = 2 1/4 (or 2.25)

4x + 18 = 10
4x = 10 - 18
4x = -8
x = -8/4
x = -2
12x – 17 = -41
12x = -41 + 17
12x = -24
x = -24/12
x = -2
12x 17= 41
Step 1: Add +17 to both sides.
12x 17+17= 41+17
12x= 24
Step 2: Divide both sides by 12.
12x12= 24
12x= 2
x= 2
