Question 570613: this is a problem that my teacher gave me and no matter how I look at it it doesn't make any sense
The perimeter of an equilateral triangle is 9 inches more than the perimeter of a square, and the side of the triangle is 6 inches longer than the side of the square. Find the side of the triangle. (Hint: An equilateral triangle has three sides the same length.)

"the side of the triangle is 6 inches longer than the side of the square" ___ t = s + 6 ___ t - 6 = s

"The perimeter of an equilateral triangle is 9 inches more than the perimeter of a square"
___ 3t = 4s + 9

substituting ___ 3t = 4(t - 6) + 9 ___ 3t = 4t - 24 + 9
