Question

what should be subtracted from 83/4 to get 21/2 ​

Answer 1

Step-by-step explanation:

Let x should be subtracted from 83/4 to get 21/2

According to the question,

$= = > \frac{83}{4} - x = \frac{21}{2} \\ = = > \frac{83 - 4x}{4} = \frac{21}{2} \\ = = > 83 - 4x = \frac{21 \times 4}{2} \\ = = > 83 - 4x = {42} \\ = = > 83 - 42 = 4x \\ = = > 41 = 4x \\ = = > x = \frac{41}{4} \: ans.$
