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.
The equation is .
There are chairs in each row.
Let the number of chairs in each row = C
3C + 2 + 13 = 8C simplify
3C + 15 = 8C subtract 3C from both sides
15 = 5C divide both sides by 5
15/5 = C = 3 chairs in each row
3(3) + 2 = 11
If she gets 13 more she has 24
And 8(3) = 24
