Calculator for Substitution Method

a11x + a12y = b1
a21x + a22y = b2

x + y = (eq.1)
x + y = (eq.2)

Solve the first equation for y:
(note that we could solve first for x as well)
y = x + (eq.3)
Plug-in the the right side of eq.3 into the eq.2
and simplify to obtain the first component of the solution vector.
x = (eq.4)
Plug-in eq.4 to the eq.1 to obtain the second component of the solution vector.
y =
