Question

Find a number if 20 less than the number is equal to 3 times the sum and twice the number is 20​

Answer 1

Answer:

Let the Number be x

20 less than the Number = x - 20

Three times the Sum of twice and the Number = 3 ( 2x + 20 )

=> x - 20 = 3 ( 2x + 20 )

=> x - 20 = 6x + 60

=> 6x - x = - 20 - 60

=> 5x = - 80

=> x = - 80/5

=> x = - 16

=> x - 20 = 3 ( 2x + 20 )

=> - 16 - 20 = 3 { 2 × ( - 16 ) + 20 }

=> - 36 = 3 ( -32 + 20 )

=> - 36 = 3 ( - 12 )

=> - 36 = - 36
