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

2) 7 and 3

15x + 12(10 - x) = 141

15x + 120 - 12x = 141

3x = 141 - 120

3x = 21

Answer:

  • 15x + 12(10 - x) = 141
  • 7 and 3

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
