Answer:
x = 5, Y = 4
Step-by-step explanation:
3x -2y = 7
-3x +9y = 21. (multiple the whole thing by 3 to get the xs to cancel)
7y = 28
y = 4
substitute y to find x
3x - 2(4) = 7
3x -8 = 7
3x = 15
x = 5
The answer is x<20. Hope that helps.
3 sixteens = 16 + 16 + 16 and 2 nines = 9 + 9 so that would be:
16 + 16 + 16 + 9 + 9 = 66
so 66 is your final answer. Hope that helps :D
