Yes, (-5,-6) is a solution to the equations!
Let
x-------------> number of cheese pizza (e<span>ach cheese pizza costs $10)
</span>y-------------> number of pepperoni pizza (each pepperoni pizza costs $13)
we know that
10x+13y <= <span>$200
x > 2y
the answer is
</span><span>This situation can be modeled by the following system of inequalities
</span>10x+13y <= $200
x > 2y
