Question

Ajutatima si pe mine va rog la ex acestea(c-104+2)x5+3=98 (dx4+20):4=12 36-42:e:(15:3-4:1)-20=10 11-(7x5-9x9:f:3):8=7

Answer 1

(c-104+2)x5+3=98-3=95
=(c-104+2)=95:5=45
=c-104=45-2=43
=c=43+104
c=147

(dx4+20):4=12
=(dx4+20)=12x4=48
=dx4=48+20=68
d=68:4
d=17

36-44:e:(15:3-4:1)-20=10
36-44:e:(15:3-4:1)=20+10=30
36-44:e:5-4=30
36-44:e:5=30+4=34
36-44:e=34x5=170
44:e=170+36=206
e=206x44
e=9064

11-(7x5-9x9:f:3):8=7
11-(7x5-9x9:f:3)=7x8=56
7x5-9x9:f:3=56+11=67
35-81:f:3=67+37=104
f:3=104+81=185
f=185x3
f=555
