If someone can give me a hint of how to set up the formula that would be great. I believe its a Arithmetic sequence formula, and I can figure it out just by adding the sequence for the answer to be 6 years.

Mei's salary starts at $16000 per year with annual raises of $1500. Janet's starting salary is $19300 with annual raises of $950 per year. After how many years will the two women be earning the same salary?
