substitute y from second equation in first to obtain x, 
then use it to find y
it has one unique solution

anonymous · Answer

5x + 3y = 7....(1) 
2x -y = 2........(2)

(2) -y=2-2x
      y=2x-2...(2)'

(2)' substitute to (1)
5x+3(2x-2)=7
11x=13
x=13/11

x substitute to (2)
2(13/11)-y=2
y=-22/26
1st solution

anonymous · Answer

5x + 3y = 7....(1) 
2x -y = 2........(2)

(2)x3 6x-3y=6...(3)

(1)+(3) 11x=13
                x=13/11

and substitute to (2)
2(13/11) - y =2
26/11 -y =2
y=4/11

this is the 2nd solution with eliminate.
sorry i got wrong about y in the 1st solution
