Step-by-step explanation:
• let x be the consecutive integer
• x + (x+1 )+(x+2)= -54 so we have three x's and the sum of 2 and 1 =3
=> 3x+3=-54
=> 3x=-54-3
=> 3x=-57 divide -57 for 3
=> x=-19
=> x+1= -19+1 = -18
=> x+2= -19+2=-17
there fore the three consecutive integers are -19,-18,-17
check
-19+-18+-17=-54
