X×5=7×9

I don't know the exact values for x, 5, 7, and 9 in your equation. However, to solve for x, you need to isolate it on one side of the equation. In this case, you can start by dividing both sides of the equation by 5 to simplify it. The equation becomes x = 7 * 9 / 5. By calculating the right side of the equation, you can find the value of x.
