Hue is arranging chairs. She can form 3 rows of a given length with 2 chairs left over, or 8 rows of that same length if she gets 13 more chairs. Complete the equation and solve it to find how many chairs are in that row length. In your equation, use the variable x to represent the number of chairs in each row.
+129899 Let x be the number of chairs in each row
So
The number of chairs she has = 3x + 2
If she adds 13 to this, then the number of chairs she will have = 8x
So we have this
3x + 2 + 13 = 8x simplify
3x + 15 = 8x subtract 3x from both sides
15 = 5x divide both sides by 5
3 = x = number of chairs on each row
