In this question, you're trying to find the solution of the equation.
First, you have to solve.
Solve the equation:
3x + 15 = 3(x+5)
use the distributive property
3x + 15 = 3x + 15
subtract 3x from both sides
15 = 15
subtract 15 from both sides
0 = 0
Since the answer came out as 0 = 0, this means that there are infinite solutions.
Answer:
Infinite solutions
