Ms. B and Ms. D are writing problems for an algebra book. Ms. B started with

Write down the problem as two equations in which equals the time in hours and

*equals the number of problems.*

Ms. B:

Ms. D:

When will Ms. B have the same number of problems written as Ms. D?

Use the Equal Values Method by setting the equations equal to each other and solving for

*x*to find the time.How many problems will they each have written at that time?

Substitute

into either of the original equations above and solve forto find how many problems they will each have written at that time.
