Question

8) x + y + y; use x = 9, and y = 10

Answer 1

We are given an expression:

`x+y+y`

We need to evaluate this expression for x =9 and y =10. Here, evaluation simply means substituting the given values of x and y into the given expression. Lets do this:

Repalcing x by 9 and y by 10, we get the following result:

`\textcolor{#FF7968}{x+y+y=9+10+10=29}`

This means, the given expression simplifies to 29, for the given values of x and y.
