Answer:
Step-by-step explanation:
subtracting your liabilities from your assets
To find the average: the sum of the values/number of values
=250+310+275+195/4
=257.5
In standard form its written
3x-12=-9
if you need help solving then here you go as well
3x-12=-9
add 12 to both sides
3x=3
divide both sides by 3
x=1
