Question

I obtained 9 when I subtracted 7 from twice a number. Then find the number​

Answer 1

Answer:

let the no. be x

ATQ , 2x-7=9

2x=9+7

2x=16

x=16/2

x=8

hence the no. is 8

Answer 2

Answer:

$2x - 7 = 9 \\ 2x = 9 + 7 \\ 2x = 16 \\ x = 16 \div 2 \\ x = 8$

This is the answer to your question.

Thanks
