x - 8 = 12 x - 8 + 8 = 12 + 8 x = 20
x=y-8 z=x+12
No, 96 = 12 x 8...
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
X=-0.6
3 - 8 + 12 = x -5 + 12 = x 7 = x Answer : 7
8 x 12 = 96
x = -8
x=8
y = x + 43y + x = 8substituting: 3*(x + 4) + x = 8 => 3x + 12 + x = 8 => 4x = -4 => x = -1and then y = x + 4 = -1 + 4 = 3.So the solution is (x, y) = (-1, 3)
y = cx when x = 8, y = 12 so that 12 = 8c which gives c = 12/8 = 1.5
X = 4
