Question

Which value of x makes the equation 0.75(x + 20) = 2 + 0.5(x 2) true?

Answer 1

`x = -56`

Explanation:

Given

`0.75(x + 20) = 2 + 0.5(x - 2)`

Required

Find x

`0.75(x + 20) = 2 + 0.5(x - 2)`

Open brackets

`0.75x + 15 = 2 + 0.5x - 1`

Collect Like Terms

`0.75x - 0.5x = 2 - 1 - 15`

`0.25x = -14`

Solve for x

`x = -(14)/(0.25)`

`x = -56`
