There are 21 boys in the class.

Step-by-step explanation

Let:

  • bbb = number of boys
  • ggg = number of girls

From the problem:

  1. Total students:
    b+g=56b+g=56b+g=56

  2. There are 14 more girls than boys:
    g=b+14g=b+14g=b+14

Substitute ggg into the first equation:

  • b+(b+14)=56b+(b+14)=56b+(b+14)=56
  • 2b+14=562b+14=562b+14=56
  • 2b=56−14=422b=56-14=422b=56−14=42
  • b=42÷2=21b=42\div 2=21b=42÷2=21

So:

  • Boys = 21
  • Girls = 21+14=3521+14=3521+14=35, and 21+35=5621+35=5621+35=56, which fits the total.

Answer: 21 boys.
