a, ( x – 35 ) – 120 = 0
=> x – 35 = 0 + 120
=> x – 35 = 120
=> x = 120 + 35
=> x = 155
Vậy : x = 155
b, 124 + ( 118 – x ) = 217
=> 118 – x = 217 – 124
=> 118 – x = 93
=> x = 118 – 93
=> x = 25
Vậy : x = 25
c, 156 – ( x + 61 ) = 82
=> x + 61 = 156 – 82
=> x + 61 = 74
=> x = 74 – 61
=> x = 13
Vậy : x = 13
