Answer:

[tex]Children = 80 - 2x[/tex]

Step-by-step explanation:

Given

[tex]Total = 80[/tex]

[tex]Men = x[/tex]

[tex]Women = x[/tex]

Required

Determine the number of children

This is calculated using:

[tex]Total = Men + Women + Children[/tex]

Substitute values for Total, Men and Women

[tex]80 = x + x+ Children[/tex]

[tex]80 = 2x + Children[/tex]

Subtract 2x from both sides

[tex]80 - 2x = 2x -2x + Children[/tex]

[tex]80 - 2x = Children[/tex]

[tex]Children = 80 - 2x[/tex]
