how do you solve this problem

3 - q = 15

3 - q = 15

Subtract 3 from both sides of the equation.

-q = 12

q = -12

Check:

3 - (-12) = 15

3 + 12 = 15

To solve the equation 3 - q = 15, you need to isolate the variable 'q' on one side of the equation. Here's how you can do it step by step:

1. Begin by eliminating the constant term on the left side of the equation. You can do this by adding 'q' to both sides of the equation:

3 - q + q = 15 + q

Simplifying, you get:

3 = 15 + q

2. Next, isolate the variable 'q' by subtracting 15 from both sides of the equation:

3 - 15 = 15 + q - 15

Simplifying, you get:

-12 = q.

Therefore, the solution to the equation 3 - q = 15 is q = -12.
