Answer 2

Step 1: Given data

Sum of two numbers, $x+y=100$

Difference of two numbers, $x-y=10$

$x=?\\y=?$

Step 2: Calculating th value of $x$ and $y$

$x+y=100---(1)$

$x-y=10---(2)$

Adding equations $(1)$ and $(2)$, we get-

$2x=110\\x=55$

substituting  $x=55$ in $(1)$

$55+y=100\\y=100-55\\y=45$

Hence, the value of $x$ and $y$ is $55$ and $45$ respectively.
