Question

How do you solve `2x+8.5=20.4`?

Answer 1

`x=5.95`

Explanation:

Subtract `8.5` from both sides of the equation so you can remove it.

`2x+cancel(8.5)=20.4-8.5`
`2x=11.9`

Divide both sides of the equation by `2` so you can solve for `x`.

`(2x)/2=11.9/2`

`:.x=5.95`

Answer 2

`2x=20.4-8.5`
`2x=11.9`
`x=5.95`
