Question

решите уравнение: 92+56 /(14-у)=100

Answer 1

$\frac{92+56}{14-y} =100$
$\frac{92+56}{14-y} =- \frac{148}{y-14}$
$-\frac{148}{y-14} =2^2+2^5$
$\frac{148}{14-y} =100$
$-\frac{4*(25y-313)}{y-14} =0$
$\frac{1}{y-14} =0$
25y=213
y=213/25
y=12 13/25

Answer 2

92+56:(14-×)=100
56:(14-×)=100-92
56:(14-×)=8
14-×=56:8
14-×=7
×=14-7
×=7
----------------------
92+56:(14-7)=100
100 = 100
