Question 232027
Ok, so let x equal the first number we don't know.

Then, since the 2nd number is 6 more than (+) the first number (x), let the second number equal x+6.

Then, since the 3rd number is "twice" the first, multiply x by 2 to let the third number equal 2x.

Now, the sum of all three numbers is 26.

So we simply add all our numbers and set them equal to 26:

x+(x+6)+2x=26

Now we combine terms to get:

4x+6=26

To get x alone, you subtract 6 from both sides:

4x=20

Then divide both sides by 4!

x=5

So since x (your first number) equals 5, the second number (x+6) is going to be 11... Then your third number (2x) has to equal 10...

Check these by adding:

5+11+10=26

These problems may be hard at first, but once you get the hang of them, they're a breeze.  Start by getting down what symbols (+,-,*) they ask for in word problems by using words like (more, less than, sum, difference, twice the first, three times, etc..)  Any more problems, just post them.  There's a lot of smart people on here.

Hope this helps!
