Solving Rational Equations With Cross Multiplication Tessshebaylo We need to set up a rational equation and solve for x. 1 x = 2 x − 21 x 2. now cross multiply. x 2 = x (2 x − 21) x 2 = 2 x 2 − 21 x 0 = x 2 − 21 x 0 = x (x − 21) x = 0, 21. however, x is a ratio so it must be greater than 0. therefore x equals 21 and the model is in the ratio 1:21 to the real racecar. solve the following rational.

Explain why multiplying both sides of an equation by the lcd sometimes produces extraneous solutions. explain the connection between the technique of cross multiplication and multiplying both sides of a rational equation by the lcd. explain how we can tell the difference between a rational expression and a rational equation. In our example, we can divide both sides of the equation by 2, giving us x 3 = 2x. subtracting x from both sides gives us 3 = 3x. finally, dividing both sides by 3 gives us 1 = x, which we can re write as x = 1. we have found x, solving our rational equation. method 2.
