Answer:

there are 200 pizzas and 300 hamburgers

Step-by-step explanation:

Let x be the hamburgers and y be the pizza

500 = y+x

500-y = x

2y+3x  = 1300

Substitute x in

2y+3(500-y) = 1300

Simplify

2y+1500-3y  = 1300

-y+1500 = 1300

y = 200

500-200 = 300

there are 200 pizzas and 300 hamburgers
