Answer

$n=-4$

Work Step by Step

We need to get the n alone, so we cancel out the subtraction by adding 3 on both sides. This leaves us with the equation 4n=7n+12. We then subtract by 7n on both sides to find that $-3n=12$. We use division to cancel out multiplication, so we divide both sides by -3 to get that $n=-4$
