9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
8x + 9x = x(8 + 9) = x(17) = 17x
7 pigs - 8 chickens + 9 pigs = 16 pigs - 8 chickens7 exes - 8 wyes + 9 exes = 16 exes - 8 wyes7x - 8y + 9x = 16x - 8y
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
9 This expression can be simplified to: 9x
9x + 4 - x + 8 = 8x + 12
44 = 9x +8 36=9x 4=x
The slope is 0.
9x + 32
x2 - 9x + 8 = (x-1)(x-8)
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
9x+8
That is an equation.Oh, you wanted to know for which values of x that equation is true? Okay...6x + 3x + 8 = 35⇔ (6x + 3x) + 8 = 35⇔ 9x + 8 = 35⇔ 9x + 8 - 8 = 35 - 8⇔ 9x + 0 = 27⇔ 9x = 27⇔ 9x / 9 = 27 / 9⇔ x = 27 / 9⇔ x = 3
8x+9=9x-18+9 = 8x+9=9x-9 = 1x=0 (:
8x + 9x = x(8 + 9) = x(17) = 17x
When x = 8 it is 78.
(x+1)(x+8)
