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.
