Step-by-step explanation:

Let the number be x

according to the question:-

x+7×5\9-3=12

x+7×5\9=12+3

x+7×5=15×9

x+7=135/5

x=27-7

x=20

Two times the number=20×2

40 is two times the number

Hope it helped

Answer 2

Step-by-step explanation:

suppose the no. be x

now according to the question

((x+7)×5)/9-3=12

(5x+35)/9-3=12

(5x+35)/9=12+3

5x+35=15×9

5x+35=135

x=(135-35)/5

x=100/5

x=20

therefore the no. is 20

and two times the no.will be

2×20=40
