(4x + 12)/(8x - 4y) = [4(x) + 4(3)]/(4(2)(x) - 4y] = 4(x + 3)/4(2x - y) = (x+ 3)/(2x - y)

It is: 4x -34x^2 -21 simplified
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
4x + 3y - 2x - 7y2x - 4y
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
If: 4x+(-12) = 8 then 4x = 20 and x = 5
