<span>The original statement would remove the two "not" values from the converse, giving "If it is April 17th, then it is Matt's birthday." Similarly, to find the inverse of the original conditional, simply flip the two statements. As such, the inverse would read "If it is Matt's birthday, then it is April 17th."</span>
X^2/(x- 9 = 81/(x - 9) This is the equation for which you want the solution. Multiplying both sides of the equation by (x - 9) we get x^2(x - 9)/(x - 9) = 81(x - 9)/(x - 9) So the (x - 9) goes out from both the denominator and the numerator and then the simplified equation becomes x^2 = 81 x ^2 = (9)^2 x = 9 So the value of the unknown variable x comes out to be 9.
