+2x+3
Step-by-step explanation:
Let's simplify step-by-step.
2 + 82 + 8 − ( −6 − 2x + 5 )
Distribute the Negative Sign:
= 2 + 82 + 8 + − 1 ( − 6 − 2x + 5 )
= 2 + 82 + 8 + − 1( − 6 ) + − 1 ( −2x ) + ( − 1 ) ( 5 )
= 2 + 82 + 8 + 6 + 2x + − 5
Combine Like Terms:
= 2 + 82 + 8 + 6 + 2x + −5
= ( 2 + 82 + 6 ) + ( 2x ) + ( 8 + − 5 )
= 90 + 2x + 3
