Answer:
13) x=n-11
15) x=3*10
Step-by-step explanation:
I used x as the variable. The questions are pretty straightforward. They are asking you to put the terms in the description on the right side of the equation. The questions = x. That was probably confusing, but it is correct. I hope this helped!
Answer:
3x + 12
Step-by-step explanation:
I got this answer because since 8x and -5x are like terms, you are able to subtract them from each other. 8x-5x is 3x. Since you cant add 12 to 5x because they aren't like terms, you leave the expression as it is right now. Finally, your answer is 3x + 12.
Hope I helped! Have a good day.
