3(x+2) = x -18 3x+6 = x -18 3x -x = -18 -6 2x = -24 x = -12

X intercept is the value of X when Y = 0 -5Y + 3X = 12 ley Y = 0 3x = 12 x = 4

3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?

6x - 12 = 3x + 12 Add twelve to both sides.6x - 12 + 12 = 3x + 12 + 12Simplify.6x = 3x + 24Subtract 3x from both sides.6x - 3x = 3x + 24 - 3xSimplify.3x = 24Divide both sides by 3.x = 8The answer is x = 8.

T = 3x + 7y; x = 4; y = 6T = 3x + 7y (substitute 4 for x, and 6 for y)T = 3(4) + 7(6) = 12 + 42 = 54
