Question

1)3,6/x-1=6/5 (решите уравнение)

Answer 1

3,6/x-1=6/5

18/5/х -1=6/5

18/5х -1=6/5

18/5х=6/5+1

18/5х=11/5

90=55х

х=18/11

Answer 2

$\frac{3,6}{x} - 1 = \frac{6}{5} \\\\\frac{3,6}{x} - 1 = \frac{6}{5} , x \neq 0\\\\\frac{18}{5} - 1 = \frac{6}{5} \\x\\\\\frac{18}{5x} - 1 = \frac{6}{5} \\\\\frac{18}{5x} = \frac{6}{5} + 1\\\\\frac{18}{5x} = \frac{11}{5} \\\\90 = 55x\\\\55x = 90\\\\x = \frac{18}{11} , x \neq 0\\\\OTBET : x = \frac{18}{11}$
