- Add: y = 9
C: an employ is paid $12 for each hour worked
First, start by distributing the 3. The equation becomes:
3x-6+5=3x-2
Then, you can simplify the left side of the equation:
3x-1=3x-2
Next, subtract 3x from both sides in an effort to make the variable be on one side of the equation. Once you do this, you will end up with:
-1=-2
Since this is not true, if means that there are no solutions.
Hope this helps!
