Question

find two numbers whose sum is 90 and difference is 35

Answer 1

Step-by-step explanation:

● Sol : -

let two no x and y

then,

x + y = 90 equation 1

x - y = 35 equation 2

solve this ,

2x = 125

x = 125/2 = 62.5

And,

putting the value of x in equation 1

x = 90 - 125/2

= 180 - 125/2 = 55/2 = 27.5

Answer 2

Answer:

Hi ❣️⭐♥️

$x + y = 90$

$x - y = 35$

Adding Equation 1 and 2,

$2x = 125$

$\implies \blue{ \boxed{x = 62.5}}$

$y = x-35$

$\implies \orange{ \boxed{\bold{y = 27.5}}}$
