Q: 5(x+10)+x

A. 6x + 15
B. 5x + 15
C. 6x + 50
D. 4x - 50

I tried to work out the problem and I came out with A. Am I right? Thanks.

No.

5(x+10)+x

5x + 50 + x = 6x + 50

Oh I see it now. I get why I got it wrong.

Could you also help me with another math problem? Every time I do the problem my answer isn't coming out right.

Okay thank you.

A. 1
B. 3
C. -3

-4n + 7 + 2n = 1

-2n - -6

n = 3
