You can put this solution on YOUR website! x+3=5...........(1)
x=3-3y..........(2)
Take (1)
x+3=5...........(1)
x=5-3
x=2
Put the value of x in (2)
x=3-3y..........(2)
2=3-3y
2-3=-3y
-1=-3y
-1/-3=-3y/-3
1/3=y
y=1/3
x,y = 2,1/3
Check
======
Put the value of x and y in (2)
x=3-3y..........(2)
2=3-3(1/3)
2=3-(3/3)
2=3-1
2=2
