Question

уравнение 3(x-1/5)=15​

Answer 1

Ответ:

$3(x - \frac{1}{5} ) = 15$

$3(x - \frac{1}{5} ) \div 3 = 15 \div 3$

$x - \frac{1}{5} = 15 \div 3$

$x - \frac{1}{5} = 5$

$x - \frac{1}{5} + \frac{1}{5} = 5 + \frac{1}{5}$

$x = 5 + \frac{1}{5}$

$\frac{25 + 1}{5}$

$\frac{26}{5}$

$x = \frac{26}{5}$
