Question

Помогите пожалуйста решить уравнение:
1/4
——— +2/5=1/2
3/4х- 1/2

Answer 1

$\frac{\frac14}{\frac34x-\frac12}+\frac25=\frac12\\\frac{\frac14}{\frac34x-\frac12}=\frac12-\frac25\\\frac{\frac14}{\frac34x-\frac12}=\frac5{10}-\frac4{10}\\\frac{\frac14}{\frac34x-\frac12}=\frac1{10}\\10\cdot\frac14=\frac34x-\frac12\\\frac34x=\frac52+\frac12\\\frac34x=3\\x=3\cdot\frac43\\x=4$
