Simplify the expression to a+bi form (-11+-5i)

(-11 + 6i) - (8 - 5i) =
When subtracting integers the subtraction sign becomes addition and the integers in the second set become their opposites therefore; the equation would change to:  (-11 + 6i) + (-8 + 5i) = Combine like terms:
(-11 + -8) + (6i + 5i) =
(-19) + (11i) = -19 + 11i

Since my answer was deleted here it is:

The variable x represents the cost per pound of meat.

The variable y represents the cost per pound of cheese.

The deli charges $4.50 for a pound of meat.

Have a great day! (this is late but for anyone else who needs it)
