Equation 1
Equation 2
From two given equations, we can find the value of both x and y by finding the value of one variable from any one of the two equations in terms of other variable and putting it to other equation.
Solving equation 1
Finding 'y' in terms of 'x' Equation 3
Putting above equation in equation 3 in 2
Putting value of 'x' in equation 3 to find the value of 'y'
