The answer is 58
By subtracting 46 from 108
Answer: 6
Step-by-step explanation: DE is 4+2 so EF would be the same if it is equal.

This is a systems of equations.
s = stamp, e = envelope

Substitute e + 9 for s.
.1(e + 9) + .13e = 2.51
Simplify.
.1e + .9 + .13e = 2.51
Simplify.
.14e + .9 = 2.51
Subtract .9 from both sides.
.14e = 1.61
Divide both sides by .14.
e = 11.5
Now, you can input e into the other equation.
11.5 + 9 = s
Simplify.
20.5 = s
s = 20.5, e = 11.5
