The outlier is $68 because it is a much smaller number than the others; it will bring averages(means) and medians down because it is so far from the other numbers
So starting with the question which is 4x-3=2x+13 All you have do is subtract 2x from 4x which is 2x So now the equation will become 2x-3=13 Minus 3 on both sides So 2x is left over 2x=16 X=8
