Question 257880: solve this equation.... -3y+20=2
Answer by unlockmath(1688)   (Show Source):
You can put this solution on YOUR website! Hello,
Here's the key to solving algebra problems---get the letter all by itself.
For example we want y by itself in this equation.
-3y+20=2 First subtract 20 from both sides to give us:
-3y=-18 Now divide both sides by -3 will be:
y=6 There we go. Y is all alone. Now plug 6 into the original problem to see if it's right.
Make sense?
