(1.03/1.02)=(1.025^x)(.9^(1-x))
We move all terms to the left:
(1.03/1.02)-((1.025^x)(.9^(1-x)))=0
We add all the numbers together, and all the variables
-((1.025^x)(.9^(-1x+1)))+(+1.03/1.02)=0
We get rid of parentheses
-((1.025^x)(.9^(-1x+1)))+1.03/1.02=0
We multiply all the terms by the denominator
-(((1.025^x)(.9^(-1x+1))))*1.02+1.03=0
We move all terms containing x to the left, all other terms to the right
-(((1.025^x)(.9^(-1x+1))))*1.02=-1.03
