Question

помогите пожалуйста ​

Answer 1

1)

$(x - 5 frac{7}{12} ) div 25 = frac{7}{25} \ (x - frac{132}{25} ) times frac{1}{25} = frac{7}{25} \ frac{25x - 132}{625} = frac{7}{25} \ 25x - 132 = 175 \ 25x = 175 + 132 \ 25x = 307 \ x = frac{307}{25} \ x = 12.28$

2)

$18 - 2x = 16 frac{3}{4} \ 18 - 2x = frac{67}{4} \ - 2x = frac{67}{4} - 18 \ - 2x = - frac{5}{4} \ x = frac{5}{8} \ x = 0.625$
