-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
You cannot solve one linear equation with two variables.
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
4x+7-3x = 15 4x-3x = 15-7 x = 8
2y = 4x + 4y = 2x + 2

x= -.5
You can't solve it. But you can simplify it to get: 4x+y=2
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
Add 4x - 2 to each side: 5x = 5 x = 1
You cannot solve one linear equation with two variables.
