Given that x = 4Y = 3 is the solution of the system ax + by = 5bx + ay = - 12, then a + B=______ ．

Given that x = 4Y = 3 is the solution of the system ax + by = 5bx + ay = - 12, then a + B=______ ．

Substituting the values of X and Y into the equations, we can get the equations about a and B, and get 4A + 3B = 54B + 3A = - 12. Solving the equations, we can get a = 8b = - 9, so a + B = - 1

If the solution of the system x = 3ax + by = 5 is the same as that of the system y = 4bx + ay = 2, then the value of a + B is ()
A. 1B. 3C. -1D. -3

Substituting x = 3 and y = 4, 3A + 4B = 5, ① 4A + 3B = 2, ②, ① + ②, 7a + 7b = 7, then a + B = 1

If the solution of the system x = 4 by + AX = 5 is the same as that of the system y = 4 BX + ay = 2, find the values of a and B
y=3

Your data is wrong
If x = 4, y = 4
So a + B = 5 and a + B = 2 are contradictory
