Question

Jane is X years old today. her brother Kenny is four years older l. after seven years of their total combined age will be 24 years. Write a linear equation for their total combination age after seven years

Answer 1

The linear equation for the total combination age is
`X+7+(X+4)+7=24`

Explanation:

If Jane is X years old today. And her brother is 4 years older then her brothers age is,

X+4.

Jane's age after 7 years = X+7

Jane's Brothers age after 7 years = (X+4)+7

So after seven years their combined age will be 24, Lets write this in an equation form,

`X+7+(X+4)+7=24`

So the linear equation for the total combination age is,

`X+7+(X+4)+7=24`
