Answer 1

Answer:

• 15x + 12(10 - x) = 141
• 7 and 3

Step-by-step explanation:

The number of people who have two-course meal is (10 - x)

Correct equation is:

• 15x + 12(10 - x) = 141

Solving for x:

• 15x + 120 - 12x = 141
• 3x = 141 - 120
• 3x = 21
• x = 7

Answer:

• Number who have three-course meal = 7
• Number who have two-course meal = 3

Answer 2

Answers:

1) 15x + 12(10 - x) = 141

2) 7 and 3

15x + 12(10 - x) = 141

15x + 120 - 12x = 141

3x = 141 - 120

3x = 21

x = 7
