Question

1000:[(11c+238):2-5]=8.Afla cat este c?

Answer 1

1000:[(11×c+238):2-5]=8
(11×c+238):2-5=8×1000
(11×c+238):2-5=8000
(11×c+238):2=8000+5
(11×c+238):2=8005
(11×c+238)=8005×2
(11×c+238)=16010
c+238=16010:11
c+238=1455rest=45
c=1455r45-238
c=1455-238+45
c=1217+45
c=1262
Sper sa fie bine

Answer 2

(11c+238)÷2-5=8×1000=8000
11c +238÷2=8000+5=8005
11c+238=8005×2=16010
11c=16010-238=15772
c=15772÷11
