x=84x\times \frac{1}{7}
Multiply both sides of the equation by 7.
x=\frac{84}{7}x
Multiply 84 and \frac{1}{7} to get \frac{84}{7}.
x=12x
Divide 84 by 7 to get 12.
x-12x=0
Subtract 12x from both sides.
-11x=0
Combine x and -12x to get -11x.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since -11 is not equal to 0, x must be equal to 0.
