-6
If: y = -x+2 and y = x-8
Then -x+2 = x-8
And: -2x = -10
So: x = 5
Therfore by substitution: x = 5 and y = -3
x8+9=81 -9 -9 x8 =72 /8 /8 x= 9
No.

8 x 0.25 = 2

Assume that the expression is x8 - 87 + 166 or x8 + 79. The expression is not factorizable since 79 is not the perfect 8th number!
Do you mean what is 8x + 9x (=17x) ?
(88-8)x8= 640
If x = 8 and y = 10 then it is 44.
x11/x8=64
64x8, also called 82x8, 83, (8x8)x8, 8x(8x), or 8x8x8, equals 512.
2x8(x8) = (2)(x8)(x8) = 2(x8+8) = 2(x16) = 2x16
