Let's go through the steps to solve the equation as shown in the image:

The equation is:

$2q + 8 + 7 = 17$

Step-by-step process:

1. Combine like terms on the left side: $2q + (8 + 7) = 2q + 15 = 17$ So, the missing term in the first blank is 15.

2. Subtract 15 from both sides: $2q = 17 - 15 = 2$ The missing term in the second blank is 2.

3. Divide both sides by 2 to isolate $q$: $q = \frac{2}{2} = 1$ The missing term in the third blank is 1.

Final solution:

The value of $q$ is 1.
