- By substitution, justify that x = − 6 is a solution to x − 2 = − x − 14.

First, let's substitute the value of x as -6 in the equation.

Now, let's solve it.

Subtract 2 from -6 to get -8.

The opposite of -6 is 6.

Subtract 14 from 6 to get -8.

Compare -8 and -8. We can see that both the LHS & RHS are equal to each other. So, hence we proved that x = − 6 is a solution of x − 2 = − x − 14.
