a=14

Step-by-step explanation:

I only have the answer for A.

Step 1: What we need to do is divide 91 by 13: 91/13=7

Step 2: Multiply 7 by 2 becasue there were 2 members in the beginning. 7*2=14

There you have your a=14

add -60 to 120 which will result in : 2x+3y=180

then subtract 2x: 3y=-2x+180

lastly, divide by 2: y= -2/3x+60

hope this is the answer you're looking for: )
