Question

the product of -4 and the number is 36 find the number one step equation​

Answer 1

x + y = 36       ....(1)

And,

xy = 315         .....(2)

We know that,

⇒  

⇒  

⇒  

x - y = 6       ....(3)

Adding (1) and (3), we get

x + x = 36 + 6 ⇒ 2x = 42

⇒ x = 21

Putting the value of x in (1), we get

21 + y = 36

⇒ y = 36 -21 = 15

Hence, the numbers are 21 and 15.
