Ms. B and Ms. D are writing problems for an algebra book. Ms. B started with 10 problems already written, and she can write 6 problems an hour. Ms. D had no problems written, but she writes 10 problems an hour. Homework Help ✎
When will Ms. B have the same number of problems written as Ms. D?
How many problems will they each have written at that time?
Write down the problem as two equations in which x equals the time in hours and y equals the number of problems.
Ms. B: y = 6x + 10
Ms. D: y = 10x + 0
Use the Equal Values Method by setting the equations equal to each other and solving for x to find the time.
Substitute x into either of the original equations above and solve for y to find how many problems they will each have written at that time.
