GIVING BRAINLIST PLZZZZ HELP ME!!!!! After Steven spent time solving the equation below, he explained his work and solution to his twin sister, Stacey.

3(5x + 7) = 30 + 15x

He shared the following with Stacey, "the equation has an infinite number of solutions because when I combined the like terms the variable cancelled out."

Was Steven correct? Why or why not? In a short video (1 minute or less) or written explanation, explain the steps you would take to solve this equation. Include step by step instructions, math vocabulary, and a brief explanation as to whether or not Steven is correct or incorrect. Be sure to explain how you know if the equation has one, infinite, or no solutions.
