Question

1.Tìm số tự nhiên x, biết :

a,(x-35)-120=0

b, 124+(118-x)=217

c, 156-(x+61)=82

Answer 1

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

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

Answer 3

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 4

à mk lộn câu a x=155 nha bạn

Answer 5

mk lộn câu a x=155 nha bạn

Answer 6

a,(x-35)-120=0

x-35=120

x=155

b, 124+(118-x)=217

118-x=93

x=25

c, 156-(x+61)=82

x+61=74

x=13
