2x - 3y = 14
2x - y = 10
eqn (1) - eqn(2) gives: -2y = 4 so that y = -2
Then, by eqn (2): 2x -(-2) = 10
2x + 2 = 10
2x = 8 and so x = 4
The solution, therefore, is (x, y) = (4, -2)
2x - 3y = 14
2x - y = 10
eqn (1) - eqn(2) gives: -2y = 4 so that y = -2
Then, by eqn (2): 2x -(-2) = 10
2x + 2 = 10
2x = 8 and so x = 4
The solution, therefore, is (x, y) = (4, -2)
2x - 3y = 14
