Question

Write an equivalent expression without parentheses and then simplify the result

8n - (7 + 6n)


A. 8n - 7 - 6n

B. 8n - 7 + 6n

C. 2n +7

D. -2n + 7

E. 2n - 7

Answer 1

The answer is E. This is distributive property, so you distribute the - to both 7 and 6n. This gives you -7 and -6n. Then you combine the like terms, which would be 8n-6n-7. This equals 2n - 7. I hope this helps!
