Question

The sum of two numbers is 60 and their difference is 30. (a) If smaller number is x, the other number is_________ . (b) The difference of numbers in term of x is________ . (c) The equation formed is______ . (d) The solution of the equation is_______ . (e) The numbers are_______ and_

Answer 1

Answer:

a)45,c)45+15=60,d)45 and 15

45-15=30

Step-by-step explanation:

x+y=60

x-y=30

2y=30

y=15

x=60-15=45

Answer 2

Answer:

60−x=60−15=45

Step-by-step explanation:

Given, one number =x

Then, other number =(60–x)

∴ Difference =(60–x)–x=60–2x

We are given that difference between two numbers is 30.

So, the equation formed is 60–2x=30

⇒ –2x=30–60

⇒ –2x=–30

⇒ 2x=30

⇒x=30/2=15

Other number=60−x=60−15=45
