Question

The sum of two numbers is 69 and their difference is 17 Find the numbers. pls solve this question for me .​

Answer 1

Step-by-step explanation:

Let one no. be x

Then the other no. =69-x

By the problem,

69-x-x=17

=>69-17=x+x

=>52=2x

=>x=52÷2

=>x=26

So, one no. is 26

And the other no. is 69-26

=43

Answer 2

$\orange{ \mathsf{ \huge{ \fbox{Solution :}}}}$

Let , the two numbers be x and y

So ,

x + y = 69 ------------ eq (1)

and

x - y = 17 ------------ eq (2)

Add equation (1) and (2) , we obtain

$\sf \hookrightarrow x + y + (x - y) = 69 + 17 \\ \\ \sf \hookrightarrow</p><p>2x = 86 \\ \\ \sf \hookrightarrow </p><p>x = 43$

Put the value of x = 43 in equation (1) , we obtain

$\sf \hookrightarrow 43 + y = 69 \\ \\ \sf \hookrightarrow</p><p>y = 69 - 43 \\ \\ \sf \hookrightarrow </p><p>y = 26$

Hence , the required numbers are 43 and 26 respectively
