Answer:

Explanation:

GK = GH + HJ + JK

But GJ = 3x + 5, HJ = x, HK = 4x - 1

Find GH:

GH = GJ - HJ
GH = (3x + 5) - x
GH = 3x + 5 - x
GH = 2x + 5

Find JK:
JK = HK - HJ
JK = (4x - 1) - x
JK = 4x - 1 - x
JK = 3x - 1

Find GK:

GK = GH + HJ + JK
GK = 2x + 5 + x + 3x - 1
GK = 6x + 4

Therefore, GK = 6x + 4
