Answer:
Step-by-step explanation:
You have that x varies directly with p*m (which means that if the result of m*p increase, x increase)
And you have too that x is inversely with y (which means that if y increase, x decrease).
Then you must get:
If the problem says that x is 2, y is 4, p is 0.5, and m is 2
the constant value should be 8, in this way:
If you replace:
The result is x=2
-4( 3a+4)
-12a - 16
-4*3a -4*4
Factor out a -4
