Answer: We are given that GH = 4x - 3 and IJ = 3x + 14.
To find x, we can set GH equal to IJ and solve for x:
4x - 3 = 3x + 14
x = 17
Therefore, x = 17.
To find the length of GH, we can substitute x = 17 into the expression for GH:
GH = 4x - 3
GH = 4(17) - 3
GH = 68 - 3
GH = 65
Therefore, the length of GH is 65.
