Question 181157
I need to solve this problem by the substitution method. I cannot figure out how to get the answer shown in the back of the book. The problem is:
x+4y=14
2x-y=1 
------------------
Solve the 1st for "x":
x = 14-4y
-------
Substitute into 2x-y = 1
2(14-4y) - y = 1
28 -8y -y = 1
-9y = -27
y = 3
-----
The x = 14-4y = 14 - 4*3 = 2
==================================
