21s = 3 |divide both sides by 21
s = 3/21
s = 1/7
21 s = 3 s = 21 3 = 7 1
To solve the equation 21 s = 3 , divide both sides by 21 to isolate s , resulting in s = 7 1 . This simplification involves reducing the fraction by dividing both the numerator and denominator by 3. The final answer is s = 7 1 .
