Answer:
Volume of sphere is 
Step-by-step explanation:
It is given that Hal says that volume of sphere is 
Volume of sphere is given by 
Now using 3.14 in place of 
Now volume of sphere is
Therefore volume of sphere when we use 3.14 in place of is
And the Hal likely error is he uses directly for calculation of volume.
Essentially, you're going to want to reverse the steps on x in order to isolate it from the rest of the variables. To do this, perform inverse operations on x. The first one of these is the multiplication of x and m, so divide both sides by m to cancel m out on the right side. Now we have y/m = x + b. The final thing to do in order to isolate x is to subtract b from both sides. This yields us y/m - b = x. This can be rearranged into x = y/m - b, which should be your answer.
You have to divide the numbers that do not have the variable y in it.
