OK, SO 4x = 12x + 32.SO 4x -12x-12x-12x+32 (subtract 12x from each side to get x on one side)SO -8x = 32 (simplify)SO -1 (-8x) = 32 (-1) (multiply each side by -1)SO 8x -32 (simplify)SO 8x / 8 = -32/8 (divide each side by eight (8) to get ""X"" by itself)SO x= -4SO x = -4.Does that help?Hope that helps!
y = 5 - 2x so 4x + 6(5 - 2x) = -2 ie 4x + 30 - 12x = -2 Subtract 30 from each side: 4x - 12x = -32 ie -8x = -32 so x = 4 and y = -3

4x+32=-4x+16x4x+32=12x-4x -4x32=8x/8 /84=x
Subtract 4 from both sides. 12x = 4x - 24 Subtract 4x from both sides. 8x = -24 x = -3 Check it. -36 + 4 = -12 - 20 -32 = -32 It checks.

y = 5 - 2x so 4x + 6(5 - 2x) = -2 ie 4x + 30 - 12x = -2 Subtract 30 from each side: 4x - 12x = -32 ie -8x = -32 so x = 4 and y = -3
4x2 = -12x, divide both sides by 4x: x = -3

4x2+12x = 4x(x+3) when factored
The factorisation is as follows: 4x² + 12x + 9 = (2x + 3)2.
8x-1 = -4x+23 8x+4x = 23+1 12x = 24 x = 2
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...
4x-2+7=174x-2 =104x =12x = 12 divided by 4 = 3
