Let us assume that the age of Janet's sister is = x
Then the age of Janet = x + 5
Now we also know that their combined age is equal to 51 years. Then we can write the equation as
x + (x + 5) = 51
2x + 5 = 51
2x = 51 -5
2x = 46
x = 46/2
= 23
So the age of Janet = x + 5
= 23 + 5
= 28 years
So the age of Janet's sister is 23 and Janet's age is 28

Hello!</h2>
The answers are:
3. Addition property of equality
4.
- Simplification
7. 
<h2>
Why?</h2>
To solve the problem, we need to start with the result of the second step:

So,
For the step 3:
Then, for the 3rd step, we have to apply the addition property of equality.
The addition property of equality states that if we add a term to one side of the equality, we need to add it to the other side of the equality, in order to not alterate the equality.
Then, applying the property, we have:

Adding 7 to both sides, we have:

For the step 4:
Now, for the 4th step, we have to simplify the expression:

Then, simplifying, we have:

For the step 7:
Simplificating, we divide each side of the equality by 6:

Have a nice day!
2.25=2 1/4
