Hi,

Let x,(x+1),(x+2) represent the three consecutive integers 

Question states***

 5x+2(x+1) =6(x+2)

 5x + 2x + 2 = 6x + 12

  7x + 2 = 6x + 12  |subtracting 6x and 2 from both sides of the Equation

    x = 10   the three consecutive integers are 10,11,12 





CHECKING our Answer***

 50 + 2*11 = 50 + 22 = 72 = 6*12
