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

The linear equation for the total combination age is

Step-by-step 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,

So the linear equation for the total combination age is,

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
