Question

Решите уровнения :115-(35+у)=39,  28-Т+35=53

Answer 1

1)
$115-(35+y)=39 \ -35-y=39-115 \ -35-y=-76 \ -y=-76+35 \ -y=-41 \ y=41$

2)
$28-t+35=53 \ -t=53-28-35 \ -t=-10 \ t=10$

Answer 2

1)
115-(35+у)=39
-35+у=39-115
35+у= -39+115
35+у=76
у=76-35
у=41

2)
28-Т+35=53
-Т=53-35-28
-Т= -10
Т= 10
