Evaluate 3x - 4y + 11 for x = -2 and y = -1

9

Step-by-step explanation:

Plug in -2 for x, and -1 for y, and solve:

3x - 4y + 11

3(-2) - 4(-1) + 11

Remember to follow PEMDAS. First, multiply. Remember, that when you multiply:

2 positive signs will result in a positive answer.

1 positive & 1 negative will result in a negative answer.

2 negative will result in a positive answer.

3 * -2 = -6

-4 * -1 = 4

-6 + 4 + 11 = 9

9 is your answer.
