First you subtract 3x because you are trying to get x alone so subtract 3x on both side so you would get 2y=-3x-4 and then divide the whole thing by 2 so you would get y=-3-4/2 and then you simplify and get y=-7/2 so y=-7/2 is your answer.
If you are saying the perimeter is 600m and the length is 22m then,
22 multiplied by 2 = 44 both side lengths
600 - 44= 556m
556m divided by 2 = 278
The width is 278m
