The way I'd do this is by elimination. Multiply 4x+y=-10 by -14x+4y=20-4x-y=105y=30y=6
As for x multiply 4x+y=-10 by -4
4x+4y=20-16x-4y=4012x=60
x=5
Answer: 1/6 package of pepperoni
Step-by-step explanation:
There were three pizzas and Mom used 1/2 package of pepperoni on all of them in an equal amount.
The fraction that each pizza got is therefore this 1/2 divided by the number of pizzas it was used on which is three.
