[tex]\sf 7p+8p-12=59\\\\\sf Add~like~terms}\\\\15p - 12=59\\\\Add~12~on~both~sides\\\\15p -12 + 12 = 59 + 12\\\\15p = 71\\\\Divide~15~on~both~sides\\\\\boxed{\bf{p = \frac{71}{15} = 4.73333333}}[/tex]
Hope I helped! If you have any other qestions or would like further explantion just let me know!! :)
