It's because Subway has better food!
.
Here's what we are told in the question:
S = M + 6981
S + M = 34529
.
We can substitute the known value of S into the second equation.
S + M = 34529
(M+6981) + M = 34529
2M + 6981 = 34529
subtract 6981 from each side
2M = 27548
Divide by 2
M = 13774
.
Let's plug it back in to make sure it's right.
13774 + 13774 + 6981 = 34529
Success!
