Question

How do you solve `-5x + 20 = 10`?

Answer 1

See a solution process below:

Explanation:

First, subtract `color(red)(20)` from each side of the equation to isolate the `x` term while keeping the equation balanced:

`-5x + 20 - color(red)(20) = 10 - color(red)(20)`

`-5x + 0 = -10`

`-5x = -10`

Next, divide each side of the equation by `color(red)(-5)` to solve for `x` while keeping the equation balanced:

`(-5x)/color(red)(-5) = (-10)/color(red)(-5)`

`(color(red)(cancel(color(black)(-5)))x)/cancel(color(red)(-5)) = 2`

`x = 2`

Answer 2

Given,

`-5x +20=10`

or, `-5x = 10-20`

or, `-5x = -10`

or, `x=(-10)/(-5) =2`

Answer 3

`x=2`

Explanation:

To isolate the `x` term, we can start by subtracting `20` from both sides to get

`-5x=-10`

Lastly, we would divide both sides by `-5` to get

`x=2`

Hope this helps!
