First integer is I, Second is I+2, Third is I+4
Three times the sum of the second and third integer is two less than twice the first integer.
3((I+2)+(I+4))+2=2I
3(I+2+I+4)+2=2I
3(2I+6)+2=2I
6I+18+2=2I
6I+20=2I Subtract 2I from each side
4I+20=0 Subtract 20 from each side
4I=-20 Divide each side by 4
I=-5 ANSWER 1: First digit is -5
I+2=-5+2=-3 ANSWER 2: Second digit is -3
I+4=-5+4=-1 ANSWER 3: Third digit is -1
CHECK
3*(-3+(-1))=2*(-5)-2
3*(-4)=(-10)-2
(-12)=(-12)
