Step 1
Put (x,y)=(2,−1) in the following equations to check if this point satisfy the equations or not.
2x−y=5
5x+2y=8
Step 2
Put (x,y)=(2,−1) in the equation 2x−y=5.
2(2)−(−1)=5
4+1=5
5=5
So, point (2,−1) satisfy this equation.
Put (x,y)=(2,−1) in the equation 5x+2y=8.
5(2)+2(−1)=8
10−2=8
8=8
So, point (2,−1) satisfy this equation.
Therefore, point (2,−1) is the solution of the system of equations.
Hence verified.
