Решите уравнение а)m+3/8m=1/4 б) у-2/9у=4 2/3 в) 2/7х+3/7х=2 7/14решите плиз

Answer 1

$a) m+ \frac{3}{8} m= \frac{1}{4}$
$\frac{8}{8} m+ \frac{3}{8} m=0.25$
$\frac{11}{8} m=0.25$
$11m=0.25*8$ 
$11m=2$
$m=2 / 11$
$m= 0. (18)$
m равно ноль целых восемнадцать в периоде

$b) y- \frac{2}{9} y=4 \frac{2}{3}$
$\frac{9}{9} y- \frac{2}{9} y= \frac{14}{3}$
$\frac{7}{9} y= \frac{14}{3}$
$y= \frac{14}{3} / \frac{7}{9}$
$y= \frac{14}{3} * \frac{9}{7}$
$y= \frac{14*9}{3*7}$
$y= \frac{126}{21}$
$y=6$

$v) \frac{2}{7} x+ \frac{3}{7}x=2 \frac{7}{14}$
$\frac{5}{7} x=2 \frac{1}{2}$
$\frac{5}{7} x= \frac{5}{2}$
$x= \frac{5}{2} / \frac{5}{7}$
$x= \frac{5}{2} * \frac{7}{5}$
$x= \frac{5*7}{2*5}$
$x= \frac{35}{10}$
$x=3.5$

Answer 2

Давайте решим уравнения по порядку.

Уравнение (а)

У нас есть уравнение \(m + \frac{3}{8}m = \frac{1}{4}\). Чтобы решить это уравнение, сначала объединим коэффициенты \(m\) слева от знака равенства: \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m + \frac{3}{8}m = \frac{1}{4}\] \[1m +
