Question

a) ( x - 25 ) - 120 = 3

b) 156 - ( x + 61 ) = 82

c) 124 + ( 118 - x ) = 217

d) ( 6x - 39 ) : 3 = 201

có ai giúp mk ko , mai mk phải lộp bài rồi , câu xin mọi ngườ đó

Answer 1

a) ( x - 25 ) - 120 = 3

x - 25 = 3 + 120

x - 25 = 123

x = 123 + 25

x = 148

Answer 2

b) 156 - ( x + 61 ) = 82

x + 61 = 156 - 82

x + 61 = 74

x = 74 - 61

x = 13

Vậy x = 13

Answer 3

c) 124 + ( 118 - x ) = 217

118 - x = 217 - 124

118 - x = 93

x = 118 - 93

x = 25

vậy x = 25

Answer 4

d) ( 6x - 39 ) : 3 = 201

6x - 39 = 201 . 3

6x - 39 = 603

6x = 603 + 39

6x = 642

x = 642 : 6

x = 107

Vậy x = 107

Answer 5

A. (x- 25) - 120 = 3

x- 25 = 3 + 120

x - 25 = 123

x = 123 + 25

x = 148.

B. 156 - (x + 61) = 82

x + 61 = 156 - 82

x + 61 =74

x = 74 - 61

x = 13.

C. 124 + (118 - x) = 217

118-x = 217 - 124

118 - x = 93

x = 118 - 93

x = 25.

D. (6x - 39) : 3 = 201

6x - 39 = 201 × 3

6x - 39 = 603

6x = 603 + 39

6x = 624

x = 624 : 6

x = 104.

Answer 6

a) (x - 25) - 120 = 3

x - 25 = 3 + 120

x - 25 = 123

x = 123 + 25

x = 148.

b) 156 - (x + 61) = 82

x + 61 = 156 - 82

x + 61 = 74

x = 74 - 61

x = 13.

c) 124 + (118 - x) = 217

118 - x = 217 - 124

118 - x = 93

x = 118 - 93

x = 25.

d) (6x - 39) : 3 = 201

6x - 39 = 201 . 3

6x - 39 = 603

6x = 603 + 39

6x = 642

x = 642 : 6

x = 107.

Answer 7

a) x-25 = 3+120
x - 25 = 123
x = 123 + 25
x = 148

Answer 8

b) x + 61 = 156 - 82
x + 61 = 74
x = 74 - 61
x = 13

Answer 9

c) 118 - x = 217 - 124
118 - x = 93
x = 118 - 93
x = 25

Answer 10

d) 6x - 39 = 201 * 3
6x - 39 = 603
6x = 603 + 39
6x = 642
x = 642 : 6
x = 107

Answer 11

a) ( X - 25 ) - 120 = 3

X-25 =120+3

X-25 =123

X =123+25

X =148

Answer 12

a) (X - 25) - 120 = 3

X - 25 = 120 - 3

X - 25 = 123

X = 123 + 25

X = 148

Answer 13

b) 156 - (X + 61) = 82

X + 61 = 156 - 82

X + 61 = 74

X = 74 - 61

X = 13
