Răspuns:

{[(a+2660:2)x3+3]x2}x5:10=4053

{[(a+1330)x3+3]x2}x5:10=4053

{[(a+1330)x3+3]x2}x5=4053x10

{[(a+1330)x3+3]x2}x5=40530

[(a+1330)x3+3]x2=40530:5

[(a+1330)x3+3]x2=8106

(a+1330)x3+3=8106:2

(a+1330)x3+3=4053

(a+1330)x3=4053-3

(a+1330)x3=4050

a+1330=4050:3

a+1330=1350

a=1350-1330

a=20

[(228+288:6):(750:25-26)]xa=5175

[(228+48):(30-26)]xa=5175

(276:4)xa=5175

69xa=5175

a=5175:69

a=75

a-[(207-105)x2+(564:4)x5]:3=1597

a-(102x2+141x5):3=1597

a-(204+705):3=1597

a-909:3=1597

a-303=1597

a=1597+303

a=1900

675:(600-595)+(72:8-386x0)xa=10800

675:5+(9-0)xa=10800

135+9xa=10800

9xa=10800-135

9xa=10665

a=10665:9

a=1185

[(a+624:6)x2+10]-170=100

(a+104)x2+10=100+170

(a+104)x2+10=270

(a+104)x2=270-10

(a+104)x2=260

a+104=260:2

a+104=130

a=130-104

a=26
