Question 87071: 3x+2y=13
2x+5y=5
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! 3x+2y=13
2x+5y=5
-------
If you want to eliminate the x terms,
Multiply the 1st equation by 2 and the 2nd equation by 3 to get:
--------------
6x+4y=26
6x+15y=15
---------
Subtract the 1st from the 2nd and solve for y:
11y=-11
y=-1
---------
Substitute to solve for x:
3x+2*-1 = 13
3x-2=13
3x=15
x=5
--------
Check your answer in the other equation:2x+5y=5
2*5+5*-1 = 5
10-5=5
5=5
==============
