You can put this solution on YOUR website! x, x+1, x+2 are the integers.
2x+6(x+1)+3(x+2)=133
2x+6x+6+3x+6=133
11x=133-12
11x=121
x=121
11x=11 answer for the first integer.
11=1=12
11+2=13
proof:
2*11+6*12+3*13=133
22+72+39=133
133=133
You can put this solution on YOUR website! Let's think about the consecutive numbers as A, A+1 and A+2.
Let's replace the words of the problem into mathematical language.
So 2A+6(A+1)+3(A+2)=133
So we simplify these: 2A+6A+6+3A+6=133, so 11A=133-12 so A=11 and A+1=11+1=12 and A+2=11+2=13
So these are the numbers 11,12,13.
