Answer:
y = x + 3
Step-by-step explanation:
So. If you multiply 99 by the other 70% (.7) that will give you the 70% of it’s worth per year. So do this four times and you get 23.7699
take 3/2 - 1/4 over to the right side of the equal sign( and then the signs change; the '+' & '-' )
then 1/2x + 3/2x =2x
and 5 -3/2 + 1/4 = 15/4
to get x alone you divide both sides by 2.
i hope this helps
