Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.

7x+8

56x^2 + 96x + 40

7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3

Assuming that what you're looking for is the values of x: x2 + 7x = 8 x2 + 7x - 8 = 0 (x + 8)(x - 1) = 0 x is equal to either -8 or 1.

5x-8 + 7x 12x-8 12x = 8 x = 8/12 x= 2/3

4x + 8 + 7x + 12 = 11x + 20

x=1

x2 + 7x - 8 = (x + 8)(x - 1)

x2+7x-8 = (x-1(x+8)

7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
