Equations are expressions with equal values

The equation that links x and y is $7x = 9y$

<h3>How to determine the equation</h3>

The ratio is given as:

$x : y = 9 : 7$

Express the ratio, as a fraction

$\frac xy = \frac 97$

Cross multiply

$7 *x = 9 * y$

Evaluate the product

$7x = 9y$

Hence, the equation that links x and y is $7x = 9y$
