Question

(7,5*3,8+7,5*6,2):(х+1)=25:х​

Answer 1

$(7,5*3,8+7,5*6,2):(x+1)=25:x\frac{7,5*3,8+7,5*6,2}{x+1} =frac{25}{x}$

ОДЗ: $left [{{xneq -1} atop {xneq 0}} right.$

$frac{7,5*(3,8+6,2)}{x+1} =frac{25}{x} \frac{7,5*10}{x+1} =frac{25}{x}\frac{75}{x+1} =frac{25}{x} \\75x=25(x+1)\75x=25x+25\75x-25x=25\50x=25\x=25:50\x=0,5$
