Answer: x = [tex]\frac{11}{5}[/tex]

Step-by-step explanation:

-2x + 7 = 3x + (-4)

-2x + 7 = 3x - 4

+2x       +2x      

       7 = 5x - 4

    +4       +4

      11  = 5x      

    ÷5  ÷5  

      [tex]\frac{11}{5}[/tex]  = x

-2x+7=3x-4


Add 2x to each side: -2x+(2x)+7=3x+2x-4


7=5x-4


Add 4 to both sides: 7+4=5x+4

11=5x


Simplify: 11/5=x
