Question

Hayden and Jamie completed 20 math problems together. Jamie completed 2 more than twice the number that Hayden completed. Let p represent the number of math problems Hayden completed.Write an equation that can be used to find the number of math problems that Jamie completed.

Answer 1

Explanation:

p + j = 20

j = 2p + 2 --> -2p + j = 2

`\binom{1 \: 1}{ - 2 \: 1} \: \binom{20}{2} = \binom{p}{j}`

Answer 2

`p+p+2=20`

Explanation:

This is what my math teacher told us, so I don't know try this.
