The equation: 6x-(x+3) =5+2x
First step in solving: 6x-x+3=5+2x
Write a clear explanation of what error has been made and what could be done to avoid the mistake.


The + 3 should be a -3.



should have been 6x-x-3=5+2x

if you have brackets with only a negative sign in front, imagine it is -1, then multiply each term inside the bracket by -1, just as if it were any other integer.
