to rog mult am nevoie de ajutorrrrrr... . ...​

Answer 1

Ą B

94+x=100 A=43+3x+3y

x=100-94 -3x=43+3y-a

x=6 x=-43/3-y+1/3a

y÷17=6 B=[152-5(x+y)]

=1/17y=6 =152-5x-y

y=102

C=300-(5y-3y)

56-2 8:(x+2)=54 =300-5y-3y

56-28/x+2=54 =300-2y

-28/x+2=54-56 =2(150-y)

-28/x+2=-2

28=(x+2)×2

28=2x+4

-2x=4-28

-2x=-24

x=12

(38+y)×3=168

114+3y=168

3y=168-114

3y=54

y=54÷3

y=18

28×(x+235)=6860

x+236=245

x=245-235

x=10

y-37=13

y=13+37

y=50
