СРОЧНО ДАЮ 20 БАЛЛОВ
$1\frac{3}{4}*(g-1,2)=5,5$
$1\frac{2}{3} *(5x-\frac{1}{2})=\frac{7}{9}$

Answer 1

1)

$1 \frac{3}{4} \times (g - 1.2) = 5.5$

$\frac{7}{4} \times (g - \frac{6}{5} ) = \frac{11}{2}$

$\frac{7}{9} g - \frac{21}{10} = \frac{11}{2}$

$35g - 42 = 110$

$35g = 110 + 42$

$35g = 152$

$g = \frac{152}{35}$

2)

$1 \frac{2}{3} \times (5x - \frac{1}{2} ) = \frac{7}{9}$

$\frac{5}{3} \times (5x - \frac{1}{2} ) = \frac{7}{9}$

$\frac{25}{3} x - \frac{5}{6} = \frac{7}{9}$

$150x - 15 = 14$

$150x = 14 + 15$

$150x = 29$

$x = \frac{29}{150}$
