Question

Via says that the model below represents the equation-2x+7=3x+(-4)

Answer 1

-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

Answer 2

Answer: x =
`(11)/(5)`

Explanation:

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

-2x + 7 = 3x - 4

+2x +2x

7 = 5x - 4

+4 +4

11 = 5x

÷5 ÷5

`(11)/(5)` = x
