Answer:

The solution is x=-10.

Explanation:

4.5*8-4.5x+36=102-2.5*3x-2.5*24

36-4.5x+36=102-7.5x-60

72-4.5x=42-7.5x

72-42=-7.5x+4.5x

30=-3x

30/ (-3) =-3x/ (-3)

x=-10

Nicolas BADIA · Answer 2 · 2018-04-10T06:54:39+0000

expand

simplify 36 - 4.5x + 36 to -4.5x + 72

simplify 102 - 7.5x - 60 to -7.5x + 42

add 7.5x to both sides

simplify -4.5x + 72 + 7.5x to 3x + 72

subtract 72 from both sides

simplify 42 - 72 to -30

divide both sides by 3

simplify 30/3 to 10

Answer: x = -10
