The solution of the system of equations x + y = 8mx − 2Y = 2m satisfies 2x-5y = - 1, and the value of M is obtained

The solution of the system of equations x + y = 8mx − 2Y = 2m satisfies 2x-5y = - 1, and the value of M is obtained

To solve the equations x + y = 8mx − 2Y = 2m, we get x = 6my = 2m, substitute x = 6m, y = 2m into 2x-5y = - 1, we get 2 × 6m-5 × 2m = - 1, we get m = - 12

The solution of the system of equations x + y = 8mx − 2Y = 2m satisfies 2x-5y = - 1, and the value of M is obtained

To solve the equations x + y = 8mx − 2Y = 2m, we get x = 6my = 2m, substitute x = 6m, y = 2m into 2x-5y = - 1, we get 2 × 6m-5 × 2m = - 1, we get m = - 12

It is known that the solution of the system of quadratic equations 2x + 5Y = 7, ax + 4Y = 6 is a solution of the equation x + y = 12, and the value of a is obtained

It can be seen from the meaning of the question that: the solution of binary linear equations satisfies the relation of X + y = 12, so: x = 12-y, substituting x = 12-y into 2x + 5Y = 7, we can get: y = - 17 / 3, x = 53 / 3, substituting y = - 17 / 3, x = 53 / 3 into ax + 4Y = 6, we can get: a = 86 / 53
