s = 6 + e
s + e = 28
We can use this system of equations to find the exact values of s and e.
We have a current value of s, so we can find the exact value of e now.
e + e + 6 = 28
Combine like terms.
2e + 6 = 28
Subtract both sides by 6.
2e = 22
Divide both sides by 2.
e = 11
Now we have an exact value of e, and can solve for the value of s.
s = 6 + 11
s = 17
