many solutions
By using the quadratic equation formula: x = -5 and x = 3
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
You cannot solve one linear equation with two variables.
subtracting gives 4x = -12 so x = -3
8x+30=4x+18 -4x -4x 4x+30=18 -30 -30 4x=-12 4x/4=-12/4 x=-3
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
2y = 4x + 4y = 2x + 2

By using the quadratic equation formula: x = -5 and x = 3
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.
