Answer:
m = 4.5
Step-by-step explanation:
2 = 2m - 7
add 7 to both sides
9 = 2m
divide by 2 on each side
4.5 = m
CHECK:
2 = 2(4.5) -7 (TRUE)
2 · 4.5 = 9
9 - 7 = 2
I hope this helps!

Hello there!
Remember that we already have one course for $35, and $22.50 for each course after that. Our total is $170.
Our equation is:
22.50x + 35 = 170
First, subtract 35 from both sides.
22.50x = 135
Divide both sides by 22.50.
x = 6
Remember to add the additional class, so x is actually 7.
Your answer is 7 courses.
I hope this helps!
