Which equation would be used to solve this word problem?
x + (x + 1) + (x + 2) = 17
(x + 1) + (x + 2) = 17
x + (x + 2) + (x + 4) = 17
2(x + 2) + 3(x + 4) = 17

Let the integers be x, x + 1, x + 2
(x + 1) + (x + 2) = 17
The second option is right.
I'll go on to solve it
(x + 1) + (x + 2) = 17
2x + 3 = 17
2x = 14
x = 7
The integers are 7, 8 and 9

the numbers are : x , ( x + 1 ) , ( x + 2 )
the sum of the second and the third = 17
( x + 1 ) + ( x + 2 ) = 17

The second one:
Let's solve it:
x +1 + x+ 2 = 17
2x = 14
x = 7
x + 1 = 8
x + 2 =9
8 + 9 = 17.
Done!

You would use the second equation:
(x + 1) + (x + 2) = 17
This way, you would solve for the first number of the three and would be able to know what the next two are.
