Isolate the logarithm with the unknown variable so that it is by itself on the right or left-hand side.
Change both sides to exponents that use 10 as the base
Because the left and right hand side of the equatsion need to be equal, 10 raised by the value on the left hand side be equalt to 10 raised to the right hand side. This is used in order to cancel out the logarithms. So both sides are rewritten in base 10:
Solve for the variable
The power of ten "cancels out" the logarithm so that only what is outside the logarithm is left, in other words x.
