Question

Write an equation for each story. Then, find the number of problems originally assigned by each teacher. If you get stuck, try drawing a diagram to represent the story.

Answer 1

Answer:

The teacher assigned 4 problems originally

Step-by-step explanation:

1) let x be the amount of problems each student got

2) equation: 5x=y (basically 30)

3) you multiply 2 by 5 because everyone got an extra two problems

4) so now its 5x + 2(5) = 30

5) simplify.

                            5x+10=30

                               -10   -10

                                5x=20

                     Answer: x=4
