Hue is arranging chairs. She can form 6 rows of a given length with 3 chairs left over, or 8 rows of that same length if she gets 11 more chairs. Write and solve an equation to find how many chairs are in that row length. How many chairs are in each row?
Let x be the number of chairs in each row.
Hue has 6x + 3 chairs.
When she gets 11 more chairs, she will have 6x + 14 chairs.
Hence, 6x + 14 = 8x.
Subtracting 6x from both sides of the equation, we get 14 = 2x.
Dividing both sides of the equation by 2, we get x = <<7=7>>7.
Thus, each row has 7 chairs. Answer: \boxed{7}.
