Start with the given equation.

Subtract 7 from both sides.

Combine like terms.

Take the square root of both sides.

or Break up the "plus/minus" to form two equations.

or Take the square root of zero to get zero.

Because negative zero is really zero, this means that there is only one solution which is .
