Hi Sarah;
S=(A-RT)/(1-R)
This can also be written as...
S/1=(A-RT)/(1-R)
Cross-multiply...
S(1-R)=(1)(A-RT)
S(1-R)=A-RT
S-SR=A-RT
Add RT to both sides...
S-SR+RT=A-RT+RT
S-SR+RT=A

I put the 1 under the S to help you understand.
When you take an exam or execute your homework, you may or may not want to do this. I do not know what your instructor wants to see.
