Answer:

x = 8

Step-by-step explanation:

3x - 5 = 2.5x + 3 - (x - 4)

<em>open parentheis</em>

3x - 5 = 2.5x + 3 - x + 4

3x - 5 = 1.5x + 7

<em>subtract 1.5x from both sides of the equation</em>

3x - 1.5x - 5 = 7

1.5x - 5 = 7

<em>add 5 to both sides of the equation</em>

1.5x = 7 + 5

1.5x = 12

<em>divide both sides of the equation by 1.5</em>

1.5x/1.5 = 12/1.5

x = 12/1.5

x = 8
