Question

Jamie is 5 years older than Ella. Jamie's age is 11 years less than three times Ella's age. The system below models the relationship between Jamie's age (j) and Ella's age (e):

j = e + 5
j = 3e − 11

Which of the following methods is correct to find Jamie's and Ella's age? (4 points)

Solve j + 5 = 3j − 11 to find the value of j.
Write the points where the graphs of the equations intersect the x-axis.
Write the points where the graphs of the equations intersect the y-axis.
Solve e + 5 = 3e − 11 to find the value of e.

Answer 1

i know the answer

Answer 2

I’d say A D you need to jus solve it out like this we will use Ella as an example

Ok so it’s set up like

E + 5 = 3e - 11

First get your variable on one side

So E - E = 3e - E

So the first E cancels out and your left with

5 = 2e - 11

Now you wanna cancel out the 11 and get the variable by it’s self

So do the opposite of what 11 is doing and add it to both sides

5 + 11 = -11 +11

So the -11 cancels out and now it’s

5 + 11 = 2e

Then simplify the addition

5 + 11 = 16

So now it’s

16 = 2e

Now do the opposite of what the 2 is doing to the E and divide it from both sides to cancel it out

16/2 = 2e/2

Then the 2e/2 is canceled out and left with the variable by its self

16/2 = e

Then simplify

16/2 = 8

So that means

E = 8

Answer 3

So now use this for the other one

Answer 4

Solve e + 5 = 3e − 11 to find the value of e.
