Answer:
-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.
