7x+8-x-7 6x+1
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
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
56x^2 + 96x + 40
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
x=1
4x + 8 + 7x + 12 = 11x + 20
7x - 8 = 2 7x = 10 x = 10/7
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
7x + 8 = 36 - 8 = - 8 -------------- 7x = 28 7x/7 = 28/7 x = 4
