The sides are all equal since this is an Equilateral Triangle. So equal both of the equations given 5x - 4 = 3x. Answer is 2

i think the answer is 6 because AB =AC.
5x-4=3x
   +4    +4                       5(2)-4=3(2) 
5x    =  3x+4                       6   = 6    
-3x       -3x
2x   =  4
2/2       4/2
   x =2
