Hello there! The value of x is 20 or -20
"20 or - 20" is one answer so you are supposed to answer 20 or -20, not choose only one.
Step-by-step explanation:

Multiply the whole equation by 25 to get rid of the denominator.
Square both sides and solve the equation.
Also don't forget to write "plus or minus" symbol when we are solving a quadratic equation by squaring both sides.
