Question

How is the answer D 1.5a - 0.5
Please show the working

Answer 1

1) 1.5a - 0.5 = 0
2) 1.5a - 0.5 + 0.5 = 0 + 0.5
3) 1.5a = 0.5
4) a = 0.5/1.5
5) a = 1/3 or .333

Answer 2

Unfortunately, it appears that y ou haven't shared the whole problem. I have no idea what answer D looks like.

I can tell you that 1.5a - 0.5 can be factored: 0.5(3a - 1)

But I don't know if that's what y ou were supposed to find.
