Hello Agnishom and thanks.

No favourite colour, although I do favour warmer colours;)

Thanks! This is how the moderator did it and it confused me because it seemed to make it more complicated than just using the reciprocal:
C=5/9(F-32)
C*9=5/9(F-32)*9
9C=5(F-32)
9C=5F-160
5F=9C+160
5f/5=9C/5 + 160/5
F=9/5C+32

Hello,

This is in regards to Question 7 at the bottom of the Equations & Formulas subsection found under The Basics in the Algebra section of the Math is Fun website. I cannot post the link, just tried. If you scroll at the bottom of that subsection, you will find the question.

This is what I did, using the reciprocal instead:
C *9/5=5/9(F-32) *9/5
9/5C=F-32
F=9/5C+32

I got the correct answer, however, you can see I did it different from what the moderator did. I was wondering if it's ok and mostly, if it will cause me problems in more complex equations.

Thank you for your help!
