    So if you add 6 to both sides of the equation what will you have?

    That's what you have on the right side true, but what do you have on the left side of the equation?

    no. \[-6 + f + 6 \]\[= 6-6 + f \]\[= 0 +f\]\[=f\]

    So when you add 6 to both sides of \(-6+f = 13\), you have \[6 -6 +f = 6+13\] \[f = 19\]
