Step-by-step explanation:
• x: number of ,children, that swam at the public pool
,
• y: number of ,adults, that swam at the public pool
We can write a system of linear equations:
Using the substitution method we can clear y from the first equation:
Replace into the second equation:
And solving for x:
Replacing x = 351 in the first equation we can find y:
Answer:
• Children: ,351
,
• Adults: ,176
