Here,
(6+7+5+q)1/2=q
So,
(18+q)1/2=q
Now, we can put value of q from options
suppose, q=18
then,
(18+18)1/2=q
36/2=q
18=q
-----
therefore, q=18

One the equation is set up, checking options is accurate and probably fast. You can also solve.

q is equal to one-half of the sum 6, 7, 5, and q:

$$(6+7+5+q) * (\frac{1}{2})=q$$
$$18 + q = 2q$$
$$q = 18$$

q= $$\frac{1}{2}$$*(6 + 7 + 5 + q)

Solving q= 18

Given : q = (6 + 7 + 5 + q)/2

2q = 18 + q

q = 18

(C)

q = (1/2)(6 + 7 + 5 + q)

q = 9 + q/2

Multiplying by 2 we have:

2q = 18 + q

q = 18
