Question

помогите пожалуйста решить уравнение...

Answer 1

$\frac{\frac29}{\frac59x-\frac12}+\frac17=\frac13\\\frac{\frac29}{\frac59x-\frac12}=\frac13-\frac17\\\frac{\frac29}{\frac59x-\frac12}=\frac7{21}-\frac3{21}\\\frac{\frac29}{\frac59x-\frac12}=\frac4{21}\\21\cdot\frac29=4\cdot\left(\frac59x-\frac12\right)\\\frac{14}3=\frac{20}9x-2\\\frac{20}9x=\frac{14}3+2\\\frac{20}9x=\frac{20}3\\x=\frac{20}3\cdot\frac9{20}\\x=3$
