Answer:
15 months
Step-by-step explanation:
35x+20=545
Subtract 20 from both side to figure out how many months he paid for....
35x+20-20=545-20
35x=525
Divide 35 on both sides....
x=15
Therefore, he has been a member for 15 months
Check:
35(15)+20=545
525+20=545
545=545
IT'S CORRECT!!!

Answer:
{x,y} = {2,7}
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = -4x + 15
// Plug this in for variable y in equation [2]
[2] 3x + 5•(-4x+15) = 41 [2] -17x = -34
// Solve equation [2] for the variable x
[2] 17x = 34 [2] x = 2
// By now we know this much :
x = 2 y = -4x+15
// Use the x value to solve for y
y = -4(2)+15 = 7
