Is this true or false (30)(-80) - 50 = 50 - (30)(-80)?

It's false.

Step-by-step explanation:

(30)(-80) - 50 = -2450

50 - (30)(-80) = 2450

False when you subtract a negative like 50 minus -2400 you get a positive, 2450, when taking a negative and subtracting a positive like -2400-50, you get a negative -2450, the answers are actually the exact opposite.  

Step-by-step explanation: 30 * -80= -2400

-2400- 50 = -2450

30 * -80=-2400

50- (-2400) = 2450
