The answer would be (5, -2). This is because when you plug in the respective values in for x and y into the equation 3x - 3y = 21, you get 21, which is the desired answer. 3x - 3y = 21 3(5) - 3(-2) = 21 15 + 6 = 21 21 = 21 Hope this helped!
The answer would be D. y=75x+300 because if you multiply 75 and 20 you would get 1500 and subtract 1800 for how much was paid and 1500 for the result of multiplying 75 and 20 Answer is D. y=75x+300
