For each plumbing repair job, Mr. Wrench charges $$N$$ dollars for coming out to the house plus $$x$$ dollars per hour that he works at the house. He charged $$\97$$ for a one-hour repair job and $$\265$$ for a five-hour repair job. What is his charge for a two-hour repair job?

Thanks in advance for the help /ᐠ｡ꞈ｡ᐟ\

$$N+1x = 97\\ N+5x = 265$$

$$\text{Subtract eq 1 from eq 2}\\ 4x = 168\\ x = \42\\ N = 97-x = 97-42 = \55$$
