Hi, My name is Chris and I'm a student having trouble solving for x in .387 = (.40  .265x)/(sqrt(1x^{2})) Any help you could give me would be much appreciated. Thanks, Chris 

Hi Chris, I would first multiply both sides by sqrt(1x^{2}) to get
Now square both sides
Simplify this exprression and use the general quadratic to solve for x. This will give you two values for x. Make sure that you verify that they are solutions by substituting into the original equation. Squareing both sides of the equation may have introduced an extraneous root. Penny
