1. 19 - 3n = -2n

Solution:

Here, we need to find the value of n.
For that we have to separate the variables on one side and constants on another side,

19-3n = -2n

Add 3n both sides, we get

19-3n +3n = -2n+3n

19 = 1n

=> n = 19

To check the answer, plugin n= 19 in the original equation, we ...
