Question

4.5(8 – x) + 36 – 2.5(3x + 24) = 102

Question 1 options:

Answer 1

`x=-(15)/(2)`

Explanation:

4.5(8 - x) + 36 - 2.5(3x + 24) = 102

Use distributive law.

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

Combine like terms.

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

Simplify.

-12x + 12 = 102

Subtract 12 from both sides.

-12x = 90

`x=-(90)/(12)`

`x=-(15)/(2)`
