Final answer:
The solution to the equation 20x + 15 = -25 is found by subtracting 15 from both sides, simplifying, and then dividing by 20, resulting in x = -2.
Step-by-step explanation:
To solve the equation 20x + 15 = -25, you can use simple algebraic techniques. Follow the steps below:
- Subtract 15 from both sides of the equation to get 20x = -25 - 15.
- Simplify the right side to obtain 20x = -40.
- Divide both sides of the equation by 20 to isolate x, which gives us x = -40 / 20.
- Simplify to find that x = -2.
Therefore, the solution to the equation is x = -2.
