Question

How do you solve `2.5x + 8= 1.5x -12`?

Answer 1

See a solution process below:

Explanation:

First, subtract `color(red)(8)` and `color(blue)(1.5x)` from each side of the equation to isolate the `x` term while keeping the equation balanced:

`-color(blue)(1.5x) + 2.5x + 8 - color(red)(8) = -color(blue)(1.5x) + 1.5x - 12 - color(red)(8)`

`(-color(blue)(1.5) + 2.5)x + 0 = 0 - 20`

`1x = -20`

`x = -20`
