<PRE><B>Question 103732</B>
2x+y+52=2y+50
2x+y+52=x-3y+131 
-------------
Simplify each equation:
1st: 2x -y = -2
2nd: x +4y = 79
------------------
Multiply 1st thru by 4 to get:
3rd: 8x -4y = -8
----------------
Add 2nd and 3rd to solve for x:
9x =71
x = 71/9
--------------------
Substitute into 2x-y = -2 to solve for y:
2(71/9) - y = -2
y = 142/9+18/9
y = 160/9
----------------
Checking in 2nd:
71/9 + 4(160/9) = 79
(71 + 640)/9 = 79
711/9 = 79
79 = 79
