Answer:

T = 25 + 12 * h

Step-by-step explanation:

First would be the full rate that has a value of 25. And for every hour that is 12.

That is to say:

T = 25 + 12 * h

h being the hours it takes to tune the piano. And this equation would reprehend what the piano tuner

Here, I'll do the first one for you.
When they are talking about a number, use "x".
Since it says twice a number, you say 2x. Or 3x for three times the number
2x+12=3x-31
Then use algebra to find x. Get the numbers on one side and all the x's on the other.
2x+12+31=3x-31+31
2x+43-2x=3x-2x
x=43

Now do the rest on your own!
