Toys

The toy shop sold the same number of balls for 62 CZK and skipping ropes for 34 CZK. Their income was 576 CZK. How many sold balls, and how many skipping ropes?

Correct answer:

x =  6
y =  6

Step-by-step explanation:


x=y
62x+34y = 576

x=y
62·x+34·y = 576

x-y = 0
62x+34y = 576

Pivot: Row 1 ↔ Row 2
62x+34y = 576
x-y = 0

Row 2 - 1/62 · Row 1 → Row 2
62x+34y = 576
-1.55y = -9.29


y = -9.29032258/-1.5483871 = 6
x = 576-34y/62 = 576-34 · 6/62 = 6

x = 6
y = 6
