Question

How do you evaluate the expression 9 + 8x + 3y + 3 + 5y x=7, y=5?

Answer 1

`=color(blue)(108`

Explanation:

The expression given is
`9 + 8x + 3y + 3 + 5y`

The values for the variables given are
`x=color(blue)(7), y=color(blue)(5`

Substituting the same in the expression:
`=9 + 8 *color(blue)((7)) + 3*color(blue)((5)) + 3 + 5 *color(blue)((5))`

`=9 + 56+ 15 + 3 + 25`

`=color(blue)(108`
