$12=11x-14x\rightarrow$ combine like terms $12=-3x\rightarrow$ divide both sides by -3 $12\div-3=-3x\div-3\rightarrow$ simplify $-4=x$ Check the soution by plugging in the value for x and determine whether the resulting equation is true. $12=11(-4)-14(-4)\rightarrow$ simplify $12=-44+56\rightarrow$ simplify $12=12$ This is true so the solution is correct.
