Question

80 people attended a meeting. There was x men and x women and the rest were children. How many children attended the meeting

Answer 1

Answer:

$Children = 80 - 2x$

Step-by-step explanation:

Given

$Total = 80$

$Men = x$

$Women = x$

Required

Determine the number of children

This is calculated using:

$Total = Men + Women + Children$

Substitute values for Total, Men and Women

$80 = x + x+ Children$

$80 = 2x + Children$

Subtract 2x from both sides

$80 - 2x = 2x -2x + Children$

$80 - 2x = Children$

$Children = 80 - 2x$
