The two equations given in the question are x = y + 10 And x = 2y + 3 Now let us substitute the value of x in the second equation with that of the first equation. We get x = 2y + 3 y + 10 = 2y + 3 y - 2y = 3 - 10 - y = - 7 y = 7 Now putting the value of y in the first equation, we get x = y + 10 = 7 + 10 = 17 So the value of x comes out to be 17 and the value of y comes out to be 7.
