7x = 18 - 2x 7x + 2x = 18 9x = 18 x = 2
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
This is only true if x = -31.
It is 9x
2x + ? = 9x9x - 2x = 7xso...2x + 7x = 9x
18 + 7x - 12 + 5x = ?18 - 12+ 7x - 5x = ?6 + 2x = ?
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
It is an equation and the value of x is 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.
