So firstly, you'll want to multiply 1/2 and (n-4) and also reverse the signs in (2n+3), and your equation will look like this: [tex] \frac{1}{2} n-2-3=3-2n-3[/tex]
Next, you'll want to combine like terms, and your equation will look like this: [tex] \frac{1}{2} n-5=2n[/tex]
Next, subtract 1/2n on each side. Your equation will look like this: [tex]-5=1 \frac{1}{2} n[/tex]
Lastly, you'll divide 1.5 on each side, and your answer should be [tex]-3 \frac{1}{3} =n[/tex]
