16n-12= -4n-18
16n+4n = -18+12
20n= -6
n= -0.3
i think this one is correct
its the same as -3/10

4(4n-3) = -2(2n+9)
==> 16n-12 = -4n-18
==> 16n+4n = 12-18
==> 20n = -6
==> n = -6/20
n = -3/10
n = -0.3

The first step is to distribute on both sides so you get; 16n-12 = -4n-18
Next, add the four n to the left-hand sign so you get; 20n-12 = -18
After that, add the 12 to the right-hand sign so you get; 20n = -6
Finally, divide both sides by 20 so your answer is n = -3/10
