Answer 1

$\huge\boxed{\underline{\bf\green{A} \: \red{N} \: \orange{S} \: \purple{W} \: \blue{E} \: \pink{R}}}$

Let x be the number

$\longrightarrow \sf5m+x-3m+7p=2m+10p \\ \\\longrightarrow \sf x + 2m + 7p = 2m + 10p \\ \\\longrightarrow \sf x + 2m - 2m = 10p - 7p \\ \\ \longrightarrow \boxed{ \sf x = 3p}$

Answer 2

Answer:

let it be x;

5m+x-3m+7p=2m+10p

2m+7p+x=2m+10p

7p+x=2m-2m+10p

7p+x=0+10p

x=10p-7p

x=3p

*x=3p...
