Question

Who do I simplify 10x - 8 + x - 7 ?

Answer 1

Add the like terms first.

Explanation:

So `10x` and `x` are like terms having the same variable, so when adding them, you get

`10x + x = 11x`

Then add up the rest and put them in the expression.

`-8-7 = -15`

So having `11x` and `-15`, you have simplified it. The final answer is

`11x-15`
