Answer 1

Step-by-step explanation:

We have given that one number is 7 more than twice another number. And the sum of the number is 22.

So, here we are talking about the two numbers let suppose that the one number is ‘x’ and the another number is ‘y’.

One number = x , the another number = y = 2x +7

Sum of both the numbers = 22

x + y = 22

x + (2x + 7)=22

3x = 22–7

3x = 15

x = (15/3)= 5

x = 5 is the final and right answer.

y = 2x +7 = 2× 5 +7= 17

Y = 17 is the final and right answer.

I hope that your doubt will be cleared up.
