Question

rezolvati in Q 1 minos 1pe 5x egal 0.5

Answer 1

$1 - \frac{1}{5} \times x = 0.5$

$1 - \frac{x}{5} = \frac{5}{10}$

$1 - \frac{x}{5} = \frac{1}{2}$

$\frac{10}{10} - \frac{2x}{10} = \frac{5}{10}$

$10 - 2x = 5$

$- 2x = 5 - 10$

$- 2x = - 5 \: | \times ( - 1)$

$2x = 5$

$x = \frac{5}{2}$
