-11
Step-by-step 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.
