first when they are in same direction they will add up and resultant will be 4+3 = 7
second when they are in opposite direction they will subtract and resultant will be 4-3 = 1
third when they are at right angle to each other  resultant will be \sqrt{4^{2}+3^{2}} = 5
Hope it clears. If you like answer then please approve it.
