Answer 1

Answer: -20

Explanation:

First, rewrite the equation plugging in the variables‘ given values.

(-12 * 5) - (4 * -3) + 19 - (3 * -3)

Next simplify everything in parentheses.

-60 - (-12) + 19 - (-9)

Subtracting a negative makes a positive, so:

-60 + 12 + 19 + 9

Finally combine like terms.

-20

Answer 2

You just need to replace the value of x and y in your expression. This gives us :

-12 * 5 - 4 * (-3) + 19 - 3*(-3) = -60 - (-12) + 19 - (-9) = -60 + 12 + 19 + 9 = - 20
