At first, weIf assumed that the two expressions are equal and then we can write the following and solve for x

5 (3x-6) = 15x-30

Then perform transposition method such as shown below

15x-30=15x-30

15x-15x=-30+30

0=0

They are equal since the derived values on both sides is the same which is zero.
