1/3X-Y=3 2X+Y=25 Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! Use Substitutionto solve each euqations, If the system does not have exactly one solution, state whethter it has no solution or infinitely many solutions.
1/3X-Y=3 2X+Y=25
-------------------
1/3X-Y=3 --> x-3y = 9 --> x = 3y+9
2X+Y=25
Sub for x into 2nd eqn
2(3y+9) + y = 25
6y+18 + y = 25
7y = 7
y = 1
-------------
Sub for y into either eqn
2x + 1 = 25
2x = 24
x = 12
