Question

11. Natasha thinks of a number and subtracts 12 from it and multiplies the result by 9.
The product now obtained is 7 times the number she thought of. What is the number?​

Answer 1

Answer:

let the number be x

Step-by-step explanation:

therefore the equation is

x-12×9=7x

x-108=7x

x-7x=108

6x=108

x=108÷6

x=18

therefore x=18

7x=7×18

=126
