Now in a mixed fraction, it would be

Hence, the water did Audrina drink altogether is

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

thats not a system of equations, that is a solution
