This will allow you to color(blue)("get the variable (a letter that takes the place of an unknown"get the variable (a letter that takes the place of an unknown color(blue)("number) and the constant (a number) by themselves so you can solve for x:")number) and the constant (a number) by themselves so you can solve for x:
xcancel-6=11
color(white)(aa)cancel+6 +6
Now, on the left side you are just left with x since (-6)+6 = 0. On the right side you end up with 17 because 11+6 = 17.
Thus,
