Answer:
Step-by-step explanation:
First digit 2,3,4,5 = 4 different digits.
Second digit 2,3,4,5 = 4 different digits.
Third digit = 1,2,3,6,7,9 = 6 different digits.
Total number of possibilities = 4*4*6 = 96
1
y = 9
-2y+6=-12
subtract 6 on both sides: -2y=-18
divide both sides by -2: y=9
I am pretty sure u got it right
