Question

How do you solve `2x + 3= - x + 3.3`?

Answer 1

`x=0.1`

Explanation:

First, add `color(red)x` to both sides.

`2x+color(red)x+3= -x+color(red)x+3.3`

Now combine the `x` terms.

`3x+3 = 3.3`

Subtract `color(blue)3` from both sides.

`3x+3-color(blue)3=3.3-color(blue)3`

Now simplify.

`3x = 0.3`

Finally, divide both sides by `color(orange)3`.

`3x div color(orange)3 = 0.3 div color(orange)3`

`color(white)"XXX"x = 0.1`
