Since point Q is the midpoint of GH, GQ must be half of GH because the midpoint bisects GH. Make 2GQ = GH in an equation.
2GQ = GH ⇒ 2(2x + 3) = 5x - 5
Distribute 2 inside the parentheses.
4x + 6 = 5x - 5
Subtract 4x from both sides.
6 = x - 5
Add 5 to both sides.
11 = x
Plug 11 for x in GQ.
GQ ⇒ 2(11) + 3
22 + 3 = 25

The length of GQ is 25.
In order to find this we must first solve for x. To do that, we must note that since Q is the midpoint of GH, then GQ must be half of what GH is. So we can write this equation.
2(GQ) = GH
Now we can plug the values of those in to solve for x.
2(2x + 3) = 5x - 5
4x + 6 = 5x - 5
4x + 11 = 5x
11 = x
Now that we have the value of x, we can plug back into GQ and find it's length.
GQ = 2x + 3
GQ = 2(11) + 3
GQ = 22 + 3
GQ = 25
