19 - 3n = - 2n
First, you'd add 3n to both sides, and your new equation would be:
19 = 1n
Then, divide both sides by one, and you get your answer.
19 = n.
Just in case, you should always check your answer.
19 - 3(19) = -38
-2(19)= -38
-38 = -38.

19-3n=-2n
19=-2n+3n
19=n
n=19
Always keep the answer on the right side of the equation.
Check:
19-3(19)=-2(19)
19-57=-38
-38=-38

Just add 3n to both sides since that's the inverse of subtracting 3n

you want to solve for n? if so...
19 - 3n = -2n
add 2n to both sides then subtract 19 to both sides.
-n=-19
divide both sides by -1
n = 19

-3n + 2n = -19
-n = -19
n = 19
Solution: {x E R | x = 19}
