8-8x=8x+18 Through simple algebra, this can be manipulated to solve for x: 8=16x+18 -10=16x -5/8=x
8x+9=9x-18+9 = 8x+9=9x-9 = 1x=0 (:
It is an expression that can be simplified to: -8x-4

3y + 18 = -8x + 3Subtract 18 from each side:3y = -8x - 15Divide each side by 3:y = (-8/3)x - 5
-8x-9+(-18) -8x-9-18 -8x-27 is your simplified answer

18 + 8x + x = = 18 + 9x = 9(2 + x) which is the factored form of the expression.
If you mean -3(x+5) = 8x+18 then -3x-15 = 8x+18 and the value of x works out as -3
3y + 18 = -8x + 3Subtract 18 from each side:3y = -8x - 15Divide each side by 3:y = (-8/3)x - 5

x² + 8x -2 = 0 x² + 8x = 2 x² + 8x + (8/2)² = 2 + (8/2)² x² + 8x + 16 = 2 + 16 (x + 4)² = 18 x + 4 = ±√18 x = -4 ±√18 x = -4 + √18 or x = -4 - √18 if you are still confused, i want you to follow the related link that explains the concept of completing the square clearly.

x2 + 8x - 2 = 0 => x2 + 8x = 2 => x2 + 8x + 16 = 2 + 16 = 18 => (x + 4)2 = 18 => x + 4 = +or- sqrt(18) = +or- 3*sqrt(2) so x = -4 +or- 3*sqrt(2)
