n-3n=14-4n or can be written as follows 1n-3n=14-4n becomes -2n =14-4n then add 4n to both sides of the equation, on the right the 4n's cancel out and on the left side -2n+4n = 2n so 2n=14 divide both sides of the equal sign by 2 to get the n by itself n=7 if you plug 7 in for n in the original equation it should equal the same on both sides of the equal sign
