Question 562341: 5x-9y=-3
4x-3y=6
Answer by mananth(16946)   (Show Source):
You can put this solution on YOUR website! 5 x -9 y = -3 .............1
4 x -3 y = 6 .............2
Eliminate y
multiply (1)by 1
Multiply (2) by -3
5 x -9 y = -3
-12 x 9 y = -18
Add the two equations
-7 x = -21
/ -7
x = 3
plug value of x in (1)
5 x + -9 y = -3
15 + -9 y = -3
-9 y = -3 -15
-9 y = -18
y = 2
