The sum of two numbers is 30 and their difference is 12, what are the two numbers
Tju [1.3M]

Step-by-step explanation:

Let the number is a <em>and</em><em> </em>b

The sum of two numbers =30

so,a+b=30 <em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>(</em><em>1</em><em>)</em>

The difference of two number =12

so,a-b=12<em> </em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>(</em><em>2</em><em>)</em>

If we add two equation (1) and (2)

we get,

a+b+a-b=30+12

2a=42

\tt{ a=\dfrac{42}{2}  }

\tt{  a=21 }

so,one number is a=21

if we put the value a in (2) equation

we get,

a-b=12

21-b=12

b=21-12

b=9

so,the another number is=b=9

\tt{ the~two~ number~ are~ 21 ~and~ 9  }
