Answer:
n = -13
Step-by-step explanation:
38 = -2n + 12
<em>Subtracting</em><em> </em><em>1</em><em>2</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
==> 38 - 12 = -2n + 12 - 12
==> 26 = -2n
<em>multiplying both sides by (-1)</em><em>:</em>
==> -26 = 2n
<em>dividing</em><em> </em><em>both</em><em> </em><em>sides by 2:</em>
==> -13 = n
