aflati x din urmatoarele egalitati:[123-24•(8:4+96:x)]:3=1si [(x+350:5)•4+6]•2=612

Answer 1

[123-24•(8:4+96:x)]:3=1

123-24•(2+96:x)=3

-24•(2+96:x)=3-123

-24•(2+96:x)=-120

24•(2+96:x)=120

2+96:x=120:24

2+96:x=5

96:x=5-2

96:x=3

x=96:3

x=32

 [(x+350:5)•4+6]•2=612

(x+70)•4+6=306

(x+70)•4=306-6

x+70=300:4

x+70=75

x=75-70

x=5
