$10-3x=40$

$\large\tt\color{purple}\underline{\underline{Solution:}}$

$\rightarrow{10-3x=40}$

See , the 10 will go at the Right hand side and become - 10 .

And the expression will be :

$\rightarrow{-3x=40-10}$

$\rightarrow{-3x=30}$

Take -3x also at Right hand side and divide with 30 .

And write x at Left hand side .

$\rightarrow{x=30/-3}$

$\rightarrow{x=-10}$

So , the answer will be -10 .
