I need to solve for Y

Here is the problem

10(y-1)=y+4

this is what I did

10(y-1)=y+4
10y-10=y+4
-y -y
9y-10=4
+10 +10
9y=14
9y/ 9 = 14/9
1.55555556=y

is this right?[/u]
 
Everyone you did was fine, but leave the answer as a fraction.
 
FYI: The exact fractional form is probably preferred to the decimal approximation.

To check the answer to any "solving" problem, plug the solution back into the original problem. If it works, then the solution is likely valid.
