The first step that we will use to separate variables and constants in the linear equation 2x + 3 = 7 is
Transposing 3 to RHS
2x + 3 = 7
If we will transpose 3 to RHS, the term with variable will remain on one side and the constants will be on other side.
So, first step is to Transpose 3 to RHS.
i.e. 2x = 7 - 3
