Step 1: Move all terms not containing <span>n</span> to the right side of the equation. Since <span>9</span> does not contain the variable to solve for, move it to the right side of the equation by subtracting <span>9</span> from both sides.
<span><span>9n = −9+9 </span><span>9n=-9+9 </span></span>Add <span><span>−9</span></span> and <span>9</span> to get <span>0</span>. <span><span>9n=0</span><span>
</span></span>Step 2: Divide each term by <span>9</span> and simplify. Divide each term in <span><span>9n = 0 by 9 </span><span>9n=0</span></span> by <span>9</span>. <span><span><span><span>9n/</span>9</span>=<span>0/9
</span></span></span>Step 3: Reduce the expression by canceling the common factors. <span><span>n=<span>0/9 </span></span></span>Divide <span>0</span> by <span>9</span> to get <span>0</span>. <span>n=<span>0</span></span>
