Answer:

6x + 11

Explanation:

1) Remove unnecessary parentheses.

-2x + 10 -(-8x-1)

2) When there is a "-" in front of an expression in parenthesis, change the sign of each term in the expression.

-2x + 10 + 8x + 1

3) Collect like terms.

-2x + 8x = 6x

6x + 10 + 1

4) Solution: 6x + 11

Answer:

11+6x

Explanation:

(–2x + 10) – (–8x – 1)

This is an algebraic expression. An algebraic expression is an expression with no equality sign. When an expression has multiple signs, the rule of BODMAS is used. That is Bracket of Division Multiplication Addition and Subtraction, and it will be solved I'm that order.

The expression in bracket would be solved first, and we do that hi opening the bracket

(–2x + 10) – (–8x – 1)

-2x+10+8x+1

Then we collect like terms

10+1+8x-2x

11+6x

An algebra can only be simplified to the lowest or simplest form.
