#### Answer

$9(6+x)=1$

#### Work Step by Step

It asks for $9$ multiplied by the sum of $6$ and $x$. The sum of $6$ and $x$ is equal to $(6+x)$. Since you want to find the product of the sum and $9$, you will get $9(6+x)$. You are also told that the product is equal to one, so your final equation will be:
$9(6+x)=1$
