You can put this solution on YOUR website! 13.20 minus blank = 9.66 13.20-x=9.66 [solve for x]
 13.20-13.20-x=9.66-13.20 [Subtract 13.20 from both sides to isolate the x]
 -x=-3.54
 -x/-1=-3.54/-1 [Multiply each side by (-1) to isolate the x]
 x=3.54
 .
 Check by plugging (x=3.54) back into the original equation:
 13.20-(3.54)=9.66
 9.66=9.66 [Checks out]
