Answer:
x = the flat fee = $1.5
y = fee per each letter sent = $0.7
Step-by-step explanation:
Let
x = the flat fee
y = fee per each letter sent
The equations
x + 35y = 26 (1)
x + 18y = 14.10 (2)
Subtract (2) from (1) to eliminate x
35y - 18y = 26 - 14.10
17y = 11.9
y = 11.9/17
y = 0.7
Substitute y = 0.7 into (1)
x + 35y = 26 (1)
x + 35(0.7) = 26
x + 24.5 = 26
x = 26 - 24.5
x = 1.5
x = the flat fee = $1.5
y = fee per each letter sent = $0.7

I was only able to come up with the answer of 1. Here is my work (don’t mind the messy handwriting I was writing with my finger on my phone)
Answer:
(x + 9) = 5
Subtract 9 from both sides
x = -4
There is your simplified answer
