Question

Evaluate the expression when x=3 and y= -2

Answer 1

-11

Explanation:

To evaluate an expression with variables, replace the variables with what the question tells you to.

Replace "x" with 3. Replace "y" with -2.

-x + 4y

= -(3) + 4(-2) Multiply 4 and -2 first to get -8

= (-3) + (-8) Add normally. -3 + (-8) is the same as (-3) - 8.

= -11 Answer

Therefore the solution is -11.
