0.0000021 you need to divide 2.1 by 10^6
D 288 because 216/3 equals 72 times that by 4 and you get 288.
Yes so i do need to doing the times and multipics then get a fraction then u will get tot eh answer
Answer:
(24, -15)
Step-by-step explanation:
-3x + 4y = 12
3x – 6y = 18
Add the two equations together to first solve for y
-2y=30
y=-15
Enter -15 into one of the equations to solve for x
-3x + 4(-15) = 12
-3x-60=12
-3x=72
x=24
Hope this helps! Please mark brainliest :)
