Final answer:
The equation 5x+5=0 has one real solution.
Step-by-step explanation:
The equation 5x+5=0 is a linear equation in one variable. To find the number of solutions, we need to solve the equation. Using the properties of linear equations, we can isolate x by subtracting 5 from both sides of the equation, which gives us 5x = -5. Then, we divide both sides by 5, resulting in x = -1. Therefore, the equation has one real solution.
