Question

решите уравнение 11 5/32-х=7 524 и 0,8-(х-0,326)=0,495

Answer 1

$11ttdisplaystylefrac{5}{32}-x=7frac{5}{24}$

$x=11ttdisplaystylefrac{5}{32}-7frac{5}{24}$

$x=11ttdisplaystylefrac{15}{96}-7frac{20}{96}$

$x=10ttdisplaystylefrac{111}{96}-7frac{20}{96}$

$x=3ttdisplaystylefrac{91}{96}$

======================================

$0,8-(x-0,326)=0,495$

$0,8-x+0,326=0,495$

$1,126-x=0,495$

$-x=0,495-1,126$

$-x=-0,631$

$x=0,631$
