Question

How do you solve `3x - 2= -20`?

Answer 1

`3x - 2 = -20`

To solve for the variable `x`, we have to make it by itself. First, add `color(blue)2` to both sides of the equation:
`3x - 2 quadcolor(blue)(+quad2) = -20 quadcolor(blue)(+quad2)`

`3x = -18`

Now divide both sides by `color(blue)3`:
`(3x)/color(blue)3 = -18/color(blue)3`

Therefore,
`x = -6`

Hope this helps!
