Which values for A and B will create infinitely many solutions for this system of equations?4x-AY=15 help me plz so confused!-4x+6y=B

infinite solutions means that u are dealing with the same line....

4x - 6y = 15
-4x + 6y = -15
--------------------add...as u can see, everything cancels
0 = 0......when u have variables that cancel, leaving u with a true statement, this means there is infinite solutions
