Answer:
2p+2+p = 20
Step-by-step explanation:
Let p represent the number of Math problems Hayden completed.
Let 2p+2 represent the number of Math problems Jamie completed.
Next, we have to<u><em> add them together</em></u> so that the total Math problems they completed will be equal to 20.
Let's solve.
- 2p+2+p = 20
- 3p+2 = 20
- 3p = 20-2
- 3p = 18
- p =
- p = 6
Therefore, Hayden completed 6 Math problems.
Next, we have to get how many problems Jamie completed.
Let's solve.
- 2p+2 = ?
- 2(6)+2 = ?
- 12+2 = ?
- 14
Therefore, Jamie completed 14 Math problems.
Let's check.
- 2p+2+p = 20
- 14+6 = 20
- 20 = 20
It's correct!
