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]
