Question

the difference between two numbers is 45 and one number is 3 times others.find the number​

Answer 1

Step-by-step explanation:

Let the first number be x.

Second number = three more than twice the first number = (2x+3)

Sum of two numbers = 45

Equation :-

x + 2x+3 = 45

or 3x+3 = 45

or 3x = 45–3

or 3x = 42

or x = 42/3

or x = 14

Ans :-

First Number = x = 14

Second Number = 2x+3 = 2(14)+3 = 28+3 = 31

Answer 2

Answer:
