[Trần Thị Huyền My]

1.Tìm số tự nhiên x, biết :

a,(x-35)-120=0

b, 124+(118-x)=217

c, 156-(x+61)=82

Answer 1

[l҉o҉n҉g҉ d҉z҉]

Ta có: a, (x - 35) - 120 = 0

(x - 35) = 0 + 120

x - 35 = 120

x = 120 + 35

x = 155

b, 124 + ( 118 - x) = 217

(118 - x) = 217 - 124

118 - x = 93

x = 118 - 93

x = 25

c, 156 - ( x + 61) = 82

x + 61  = 156 - 82

x + 61 = 74

x = 74 - 61

x = 13

Answer 2

[The love of Shinichi and Ran is imm...]

a,=>x-35=120

x=120+35

x=165

b,=>118-x=217-124

118-x=93

x=118-93

x=25

c,=>x+61=156-82

x+61=74

x=74-61

x=13
