Question 707609
First you need to leave the variable on one side so transpose -10 to the other side: 
22=8f-10
-10 will then become positive like this: 
22+10=8f
Then add: 
32=8f
Now you need to transpose 8 to the other side to leave the variable.
Do it by dividing the 8 on both sides:
32/8 = 8f/8
Answer:
4=f
