You have the following equation:
14 - 3x = 46 - x
In order to solvet the previous equation for x, you proceed as follow:
14 - 3x = 46 - x subtract 14 and sum x both sides
-3x + x = 46 - 14 simplify similar terms
-2x = 32 divide by -2 both sides
x = 32/(-2) = -16
x = -16
Hence, the solution of the given equation is x = -16
