Answer
6 is a solution.
Work Step by Step
To determine which of the numbers in the set [10,6,8] solves the equation, isolate the variable.
$5n+4=34$
Subtract 4 from each side.
$5n=30$ We already know the number has to be a factor of 30, so you can eliminate 8 at this point.
Now divide both sides by 5.
$n=6$ Bingo!
