помогите пожалуйста решить)​

Answer 1

$1)\\\frac{4x - 1}{5} = \frac{1}{2} \\\\2(4x=1)=5\\\\8x - 2 = 5\\\\8x = 5 + 2\\\\8x = 7\\\\PEIIIEHUE:\\x = \frac{7}{8}\\\\\\2)\\\frac{2x + 1}{3} = \frac{1}{2} \\\\2(2x+1)=3\\\\4x + 2 = 3\\\\4x = 3 - 2\\\\4x = 1\\\\PEIIIEHUE:\\x = \frac{1}{4}\\\\\\3)\\\frac{3 - 2}{x} = \frac{1}{3} \\\\\frac{3 - 2}{x} = \frac{1}{3} , x \neq 0\\\\\frac{1}{x} = \frac{1}{3} \\\\x = 3 , x \neq 0\\\\PEIIIEHUE:\\x = 3$
