You can use two variables in an equation, just substitute it in.
4n-7=9
4n= 9+7
4n= 16
n= 16/4
N= 4
Answer:
Subtract from the dividend an easy multiple of the divisor
Record the partial quotient in a column to the right of the problem.
Repeat until the dividend has been reduced to zero or the remainder is less than the divisor.
Add the partial quotients to find the quotient.
Step-by-step explanation:

For now, we can’t get a definite answer. We can model with an equation, but we cannot find the absolute amount Jocelyn will earn, as her hourly rates are both variables. All we must do to create an equation for this is multiply the amount of hours by the rate and add. You could model like this:
25n + 15x = total amount earned
Answer:
Let's call the first studio, yoga studio A.
Let's call the second studio, yoga studio B.
The equations:
Yoga Studio A: y=10x+55
Yoga Studio B: y=12.5x+25
So, for 12 classes:
Yoga Studio A: y=10(12)+55, y=175
Yoga Studio B: y=12.5(12)+25, y=175
These two numbers are equal, so Griffin is right.
For 10 classes:
Yoga Studio A: y=10(10)+55, y=155
Yoga Studio B: y=12.5(10)+25, y=150.
These two numbers are not equal, so Gigi is wrong.
Let me know if this helps!
