Step-by-step explanation:

$3.7x - 3 = 18 \\ 3.7x = 21 \\ x = \frac{21}{3.7} = \frac{210}{37}$

Answer 2

Answer:

>> Let the number be x.

>> 3.7 times of x will be 3.7*x

>> 3.7 times a number decreased by 3 equal 18.

>> So,

         3.7*x - 3 = 18

         3.7*x = 21

         x = 5.68

>> Hence the number will be 5.68 or 210/37 (as 37 is a prime number).
