Question

1. The sum of two numbers is 7. The difference of five times the first number and three times the
second number is 3. Find the numbers.​

Answer 1

Answer:

Let the number be a and b

So,

a+b =7

5a-3b =3

Now eliminate b

3a +3b =21(multiplying whole equation by 3)

5a-3b=3

Now add ,

You will get

8a=24

a=3

So,b =4
