Question 12859
What are 3 consecutive numbers with the sum of 600?
Consecutive means they are 3 numbers in a row; ex. 2,3,4
So we will let x be our first number, the next number(since it comes right after the first) is going to be x+1, and the third number (since it comes 2 numbers after our first) will be x+2.
So our equation will be:
x+(x+1)+(x+2)=600
Now we solve the equation; we can add all the x's together because they are like terms;
3x+3=600; 
Now subtract 3 from both sides;
3x+3-3=600-3
3x=597
now both sides by 3;
{{{3x/3=597/3}}}
x=199
Now we know what the first number is, and since they are consecutive they will be,
199, 200, 201

Hope you understand!
