Question

One number is 4 less than a second number. Twice the second number is 16 less than 5

Answer 1

Answer:

The first number = 8

The second number =  12

Step-by-step explanation:

let the given first number  = x

And the given second number  =  y

Now, according to the question:

x = y - 4

2 y = 5x - 16

Now substitute the value of x in (2)

2 y = 5x - 16  ⇒  2 y =  5(y -4) -  16

or, 2y = 5 y - 20 - 16

or, - 3 y = - 36

⇒  y =  36/3 = 12

So , the second number y =  12

and x  =  12  - 4 = 12 - 4 = 8

Hence, the first number = 8

and  the second number y =  12
