Răspuns:

94+x=100<=>x=100-94<=>x=6

y:17=6 <=>y=6*17<=>y=102

A=43+3x+3y

A=43+3*6+3*102

A=43+18+306

A=367

56-28:(x+2)=54

28:(x+2)=56-54

28:(x+2)=2

x+2=28:2

x+2=14

x=14-2

x=12

(38+y)*3=168

114+3y=168

3y=168-114

3y=54

y=18

B=[152-5(x+y)]

B=[152-5(12+18)]

B=[152-5*30]

B=(152-150)

B=2

x+235=6860:28

x+235=245

x=245-235

x=10

y-37=13

y=13+37

y=50

C=300-(5y-3x)

C=300-(5*50-3*10)

C=300- 250-30

C=50-30

C=20
