Answer:
The answer is: Each kid have 200 & 210 marbles.
Step-by-step explanation:
The first kid has formed x heaps, so the second kid has formed (70 - x) heaps.
By the problem
5x +7 (70 - x) = 410 (First kid arranges 5 marbles and second kid arranges 7 marbles in each heap)
5x +490 -7x = 410
2x = 80
x = 40
=>Since (70 -x) = 70 - 40 = 30
First kid has = 5 x 40 = 200 marbles
Sedcond kid has = 70 x 30 = 210 marbles
