0.1x-0.45=0.03x-0.15

We move all terms to the left:

0.1x-0.45-(0.03x-0.15)=0

We get rid of parentheses

0.1x-0.03x+0.15-0.45=0

We add all the numbers together, and all the variables

0.07x-0.3=0

We move all terms containing x to the left, all other terms to the right

0.07x=0.3

x=0.3/0.07

x=4+0.02/0.07
