Answer:
The three integers are 13,14,15
Step-by-step explanation:
Let x be the first integer
x+1 be the second integer
x+2 be the third integer
The sum of the three integers is 42
x+ (x+1) + (x+2) = 42
Combine like terms
3x+3 = 42
Subtract 3 from each side
3x+3-3 = 42-3
3x= 39
Divide by 3
3x/3 = 39/3
x = 13
x+1 = 14
x+2 = 15
The three integers are 13,14,15
