Answer:
System of equations: 8x + 2y = 82 and 4x + 2y = 54
Explanation:
Given that:
8 solo acts and 2 ensemble acts will last for 82 minutes
4 solo acts and 2 ensemble acts will last for 54 minutes
Let,
x be the minutes solo acts lasts
y be the minutes ensemble acts lasts
According to given statement;
8x + 2y = 82
4x + 2y = 54
Hence,
System of equations: 8x + 2y = 82 and 4x + 2y = 54
