Distribute 1/2 to <span>(n – 4):
</span>
<span>
Subtract (2n + 3):
</span>
<span>
Your equation should now look like this:
</span>
<span>
Combine like terms on both sides:
</span>
<span>
Subtract 1/2n from both sides:
</span>
<span>
Divide both sides by -5/2 to get n by itself:
</span>
<span>
The value of n is
2.</span>
