multiply the first by 4
4x-12y = 4
4x + 5y = 4
subtract them:
-17u = 0
y = 0
back into the first:
x - 0 = 1
x = 1
X-3y=1
4x+5y=4
Solve the system of equations.

x = (3 y + 1)
4(3y+1) + 5 y = 4
12 y + 4 + 5 y = 4
17 y = 0
y = 0
x = 3*0 + 1 = 1
(1,0)
4(3y+1) + 5 y = 4
12 y + 4 + 5 y = 4
17 y = 0
y = 0
x = 3*0 + 1 = 1
