**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)
