Answer:
Step-by-step explanation:
8/3=3(c+5/3)
multiply both sides by 3
8=9(c+5/3)
divide both sides by 9
8/9=c+5/3
subtract 5/3 from both sides
c=8/9-5/3
change 5/3 to 15/9
c=8/9-15/9
c=-7/9
To do this question I recommend dividing each number by the lowest prime number you can each time.
36/2=18
18/2=9
9/3=3
Since 3 is prime we stop there. The prime factors of 36 are therefore 2,2,3, and 3. I would write this as 36=2^2x3^2
22 is simpler as it is just 2x11
