Since the solution will be of the form z=k it has one solution...
3.5z=2.25z-4.25+6.25
3.5z=2.25z+2
1.25z=2
z=1.6
A single solution...

Answer:
If all three digits need to be the same (I assume that's what aaa means) it's 333
Step-by-step explanation:
For a number XYZ to be divisible by 9, X+Y+Z must be divisible by 9. Here's why:
X*100 + Y * 10 + Z = X + Y + Z + 99*X + 9*Y = X + Y + Z + 9(11X + Y)
So we need to find the smallest a so that a+a+a = 3a is divisible by 9. The smallest would be 0, but 000 is not a real 3-digit number. The next one is 3.
