The equations 2x − y = − 33x + y = 8 and ax + by = 2aX − by = 4 have the same solution, and the values of a and B are obtained

The equations 2x − y = − 33x + y = 8 and ax + by = 2aX − by = 4 have the same solution, and the values of a and B are obtained

By solving the equations 2x − y = − 33x + y = 8, we get x = 1y = 5. By substituting the equations ax + by = 2aX − by = 4, we get a = 3B = − 15
