Equations are expressions with equal values
The equation that links x and y is ![7x = 9y](https://tex.z-dn.net/?f=7x%20%3D%209y)
<h3>How to determine the equation</h3>
The ratio is given as:
![x : y = 9 : 7](https://tex.z-dn.net/?f=x%20%3A%20y%20%3D%209%20%3A%207)
Express the ratio, as a fraction
![\frac xy = \frac 97](https://tex.z-dn.net/?f=%5Cfrac%20xy%20%3D%20%5Cfrac%2097)
Cross multiply
![7 *x = 9 * y](https://tex.z-dn.net/?f=7%20%2Ax%20%3D%209%20%2A%20y)
Evaluate the product
![7x = 9y](https://tex.z-dn.net/?f=7x%20%3D%209y)
Hence, the equation that links x and y is ![7x = 9y](https://tex.z-dn.net/?f=7x%20%3D%209y)
