Question

The sum of 2 numbers is 10 and their diffrence is 8.

Answer 1

Answer:

Step-by-step explanation:

Foam an linear equation on the basis of given information.suppose two numbers is x and y .

sum of two numbers is 10

So, x+y=10 and second equation x-y=8 now by solving this two equations we get x=9 and y=1

Answer 2

$\Large{\textbf{\underline{\underline{According\;to\;the\;Questions}}}}$

Given,

$\textbf{\underline{Sum\;of\;two\;number\;is\;10}}$

$\textbf{\underline{Difference\;is\;8}}$

Assume

Number be x and y respectively

So,

x + y = 10 ....... (1)

x - y = 8 ........... (2)

$\Large{\boxed{\bigstar{{Adding\;both\;Equation :-}}}}$

x + y + (x - y) = 10 + 8

x + y + x - y = 10 + 8

2x = 10 + 8

2x = 18

$\rm \: \: \: \: \: \: \: \: \:x=\dfrac{\cancel{18}}{\cancel{2}}$

x = 9

Hence,

$\Large{\boxed{\bigstar{{First\;number= 9}}}}$

$\Large{\boxed{\bigstar{{Second\;number:-}}}}$

x + y = 10

9 + y = 10

y = 10 - 9

y = 1

Therefore,

$\huge{\boxed{\sf\:{First\;number = 9\;and\;Second\;number = 1}}}$
