Question

The sum of two numbers is 60 and theor difference is 30 then the numbers are

Answer 1

Answer:

45 and 15

Step-by-step explanation:

let the no.s be X and y

then

x+y=60. eq 1

x-y =30. eq2

adding both the equations

x+y+x-y = 60+30

2x =90

x = 45

x+y= 60

y=60-45

y=15

so the no.s are 45 and 15

Answer 2

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
