It is done by many methods
for example :
trial and error method
x + 5 = 7
put the value of x as 1
LHS = 1+5
=6
RHS = 7
6 ≠ 7
LHS ≠ RHS
put the value of x as 2
LHS = 2+5
=7
RHS = 7
7 = 7
LHS = RHS
x = 2
There are many ways
x + 5 = 7
additive inverse of +5 = -5
add -5 to both the sides
x+5-5=7-5
x=2
x + 5 = 7
x = 7-5
=2

Finding the value of x,we take an example ::
if,it's given,
LHS RHS
x + 4 = 12
So x = 12 - 4
= X = 8
Or,, we can take the x at one side and the numbers at one side and then solve it,this also led us know about the value of the literals
