Lets discuss problems and strategies related to GMAT / CAT / MBA quantitative ability here.
@lalithasrip asked : “what is the value of P if the equation are consistent and x not equal to 0 and not equal to Y ???”
The equations are
5x+4y=32
2py+15x=96
multiply 1st eq by 3
so it becomes 15x + 12y = 96
and 2nd eq is 15x + 2py = 96
subtract both
u will get 2py = 12
2p = 12
p = 6
