Question

How do you simplify `-10+ 4k - 10+ 4k`?

Answer 1

`8k - 20`

Explanation:

When simplifying, you want to collect like terms and then add or subtract.

Collecting like terms, we rearrange the expression to get
`4k + 4k - 10 - 10`

Then we simply add: `4k + 4k = 8k`
and subtract: `-10-10 = -20`
to simplify these two parts, then put them together to get
`8k - 20`
