Each month, Liz pays $35 to her phone company just to use the phone. Each text she sends costs her an additional $0.05. In March, her phone bill was $72.60. In April, her phone bill was $65.85. How many texts did she send each month?

Okay, is there a way to solve this without writing two equations, or do I have to solve an equation per month? (sorry idk if my question makes sense lol)

I think you need one equation per unknown...you have two unknowns so you need two equations.
