Question 585291: 3x+2y=13
2x-y=4
Answer by mananth(16946)   (Show Source):
You can put this solution on YOUR website! 3 x + 2 y = 13 .............1
2 x -1 y = 4 .............2
Eliminate y
multiply (1)by 1
Multiply (2) by 2
3 x 2 y = 13
4 x -2 y = 8
Add the two equations
7 x = 21
/ 7
x = 3
plug value of x in (1)
3 x + 2 y = 13
9 + 2 y = 13
2 y = 13 -9
2 y = 4
y = 2
(3,2) is the solution
