Answer 1

2m + n.....when m = 7 and n = 9

2(7) + 9 =
14 + 9 =
23 <==

** its just a matter of subbing and solving :)

Answer 2

If "
`m`" =
`7` & if "
`n`" =
`9`

Then your problem becomes:
`2(7) + 9`

Now, let's find what your answer equals:
`Step^1: 2(7) = 14,right? \\ Step^2: 14 + 9 = ? \\Step^3:Answer: 23`
