Решить уравнение. Помогите пожалуйста

Answer 1

$1)\frac{3x-7}{x-1}-\frac{x+1}{x-1}=0\\\\\frac{3x-7-x-1}{x-1}=0\\\\\frac{2x-8}{x-1}=0\\\\\left \{ {{2x-8=0} \atop {x-1\neq0 }} \right. \\\\\left\{ {{2x=8} \atop {x\neq1 }} \right.\\\\x=4$

$\frac{x}{x+5} -\frac{25}{x^{2}+5x }=0\\\\\frac{x}{x+5}-\frac{25}{x(x+5)}=0\\\\\frac{x^{2}-25 }{x(x+5)}=0\\\\\frac{(x+5)(x-5)}{x(x+5)}=0\\\\\left \{ {{\frac{x-5}{x}=0 } \atop {x\neq 0,x\neq-5 }} \right.\\\\x-5=0\\\\x=5$
