You can put this solution on YOUR website!
Eq 1 states: 3x = 3 + 2y
E1 2 states: (-4/3)x + y = 1/3
-------------------
Rewrite the equations:
Eq 1 : 3x -2y = 3
Eq 2 :-4x +3y = 1
----------------
Multiply Eq 1 by 3 and Eq 2 by 2 to get:
Eq 3: 9x -6y = 9
Eq 2:-8x +6y = 2
------------------
Add the wo equations to get:
x = 11
----------
Substitute into Eq 1 to solve for y:
3*11 = 3 + 2y
30 = 2y
y = 15
---------------
Solution : x=11, y=15
================
