Answer 1

GIven:

Sum of two numbers is 71.

Difference of two number is 35.

x is larger than y.

Consider the two numbers as x and y. The two equations can be represented as.

$\begin{gathered} x+y=71\ldots\ldots\ldots.(1) \\ x-y=35\ldots\ldots\ldots.(2) \end{gathered}$

On solving equation (1) and (2),

$\begin{gathered} 2x=106 \\ x=\frac{106}{2} \\ x=53 \end{gathered}$

Now, substitute the value of x in equation (1).

$\begin{gathered} 53+y=71 \\ y=71-53 \\ y=18 \end{gathered}$

Hence, the value of x is 53 and the value of y is 18.
