Question 1010118
Solve 5y-10x=15 for y.


ADDITION PROP of EQLTY, Step 1: 5y=15+10x


MULTIPLICATION PROP of EQLTY, Step 2: y=15+10x/5 
Mistake in grouping


DISTRIBUTIVE PROPERTY, Step 3: y=3+10x
The needed grouping WAS observed, but one of the computational parts was done wrongly.  


The correct result should be  y=3+2x.
