Question

4 1/3х-2 2/3х=5
3/5х+2/15=10

Answer 1

$1) 4\frac{1}{3} x - 2\frac{2}{3} x = 5$

$\frac{13}{3} x -\frac{8}{3} x = 5$

$\frac{5}{3} x = 5$

$x = 3$

$2) \frac{3}{5} x + \frac{2}{15} =10$ (умножаем обе части на 15)

$15 * \frac{3}{5}x + 15 * \frac{2}{15} = 15 * 10$

$3 * 3x + 2 = 150$

$9x+2=150$

$9x = 150 - 2$

$9x=148$

$x = 16\frac{4}{9}$
