Answer:
A = 15
B = 3
Explanation:
Since Team A has 12 more points than team B, then,
A - 12 = B
A = B + 12 ( equation 1 )
team A has 5 times as many points as team B, so,
5B = A. ( equation 2 )
Substitute equation 1 into equation 2
A = B + 12
5B = B + 12
5B - B = 12
4B = 12
B = 3
we'll substitute the answer into equation 2
5B = A
5(3) = A
A = 15
I hope this helps :D
have a nice day dear...
