Find x - 3y if x = 3 and y = -2.

Solution:

Given expression is x - 3y

Let f(x, y) = x - 3y

If x = 3 and y = -2, let us evaluate the expression for the values.

Substitute the given values in the given expression.

= 3 - 3(-2)

= 3 + 6

= 9

Therefore, the value of f(x, y) = 9.

Find x - 3y if x = 3 and y = -2.

Summary:

If x = 3 and y = -2, then x - 3y is 9.
