Anyone Know System of Equations

I am going to be honest...I am the worst at this, lol. I know you guys hate answering more than like 2 questions, but I promise, I need help! I do not like cheating, so if you just want to show me in more detail how to do this; than my crappy teacher...than I am good. :-) Thanks to all in advance!!!

1. A possible step toward solving these equations by addition could be:

-2x + 5y = -3
-11 + 2x = -3y

A. solving for x in the equation 2x = -14

B. solving for y in the equation 8y = 14

C. solving for y in the equation 8y = 8

D. multiplying 2x + 3y = 11 by -1



2. A step toward solving these equations by addition could be:

12x - 3y = 4
-2 - 2y = -4x

A. multiplying 12x - 3y = 4 by 2

B. add 12x and -4 x

C. adding 24x to 12x

D. multiply -2 - 2y = -4x by -3



3. Moving van company A charges a $40.00 fee to rent a van. In addition to this fee, they charge $0.35 a mile. Moving van company B charges $14.00 a day and $0.30 a mile to rent their vans. Aaron needs to rent a moving van for 5 days. He will be driving 120 miles. Which company should Aaron choose if he wants to spend the least amount of money?



A. Company B

B. Company A

C. It is the same amount for both company A and company B.

D. Not enough information given to answer the question.



4. A possible step toward solving these equations by addition could be:

8y + 3x = 7
-3x + 4y = 2

A. subtract 3 from 8

B. adding 8y and 4y

C. multiplying 4y - 3x = 2 by -1

D. subtracting 2 from 7
