If: x+16 = 9x then x = 2
(x + 8)(x + 2)
x*x - 8x +16 = 0 x*x = 8x + 16 x - 16 = _/8x x_/-4 = 2 x = 2
The answer is very easy: x= 16 ________ 2 +(2*5) x= 16 ____ 12 x = 4 __ 3
2(x - 2)(x - 4)
If: x+16 = 9x then x = 2
x = 14
x=-16
16
2x2=4x4=16
(x, y) = (3, 2)
(x + 8)(x + 2)
x*x - 8x +16 = 0 x*x = 8x + 16 x - 16 = _/8x x_/-4 = 2 x = 2
The answer is very easy: x= 16 ________ 2 +(2*5) x= 16 ____ 12 x = 4 __ 3
2(x - 2)(x - 4)
You plug in the values of x and y and solve 12x + 16y = ? 12(1) + 16(2) = 12 + 32 = 44
x=16
