$x+\frac{4}{x}=25-7$
Learn how to solve problems step by step online. Solve the rational equation x+4/x+7=25. Group the terms of the equation by moving the terms that have the variable x to the left side, and those that do not have it to the right side. Subtract the values 25 and -7. We need to isolate the dependent variable x, we can do that by simultaneously subtracting \frac{4}{x} from both sides of the equation. Canceling terms on both sides.
