How do you determine whether the given ordered pair (2, -3) is a solution of the system #x=2y+8# and #2x+y=1#?
Just put the values of 'x' and 'y' in both of the equations and see if L.H.S and R.H.S are coming equal in each case.
This is how we do it:
Putting the value of x and y in the equation
For equation 2
putting the value of x and y in the equation
