7x-5x=8 2x=8 x=4
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6

7x + 9 = 6x + 17 7x - 6x = 17 -9 x = 8
The equation can be solved by isolating the variables from the numbers. The answer would be 4x = 8, which equals 2.
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
7x-5x=8 2x=8 x=4
7x + 8 = 36 - 8 = - 8 -------------- 7x = 28 7x/7 = 28/7 x = 4
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.
8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3
-8 + 7x = x - 506x = -42x = -6
4x+5=7x-8 the ansewr is 3.25
Subtract 7x from each side: 8 = -9 Not possible, game over.
x = 8
x=12
x=1
