1. Start by distributing the -3 on the right side of the equation:
-5x - x + 15 = -6x + 15
2. Combine like terms on the left side of the equation:
-6x + 15 = -6x + 15
3. Subtract -6x from both sides of the equation to isolate x:
15 = 15
4. Since both sides of the equation are equal, this means that the equation is an identity, and there are infinite solutions.
5. There are infinite solutions because the equation simplifies to a true statement where x can be any value and still satisfy the equation.
