(20+4x)82003 = 82005
20 + 4x = 82005 : 82003
20 + 4x = 82
20 + 4x = 64
4x = 64 - 20
4x = 44
x = 44 : 4
x = 11
Vậy x = 11
(20 + 4x ) . 82003 = 82005
20 + 4x = 82005 - 82003
20 + 4x = 82
20 + 4x = 64
4x = 64 - 20
4x = 44
x = 44 : 4
x = 11
(20+4x) . 82003 =82005
20+ 4x = 82005: 82003
20+ 4x = 82
20+ 4x = 64
4x = 64 - 20
4x = 44
x = 44:4
x =11
