Solve by using elimination 3x-2y=1. 8x+3y=2

Elminate the y's

multiiply first euation by 3 and multiply 2nd equation by 2 and ad them

9x-6y=3

16x+6y=4 +

25x+0y=7

25x=7

divide both sides by 25

x=7/25

sub back

3x-2y=1

3 (7/25) - 2y=1

21/25-2y=1

note: 1=25/25

minus 21/25 fromboth sides

-2y=4/25

divide both sides by - 2 (or times - 1/2)

y=4/-50

y=-2/25

x=7/25

y=-2/25

(-2/25,7/25)
