Answer 1

1)

4x+5 = 87:3

4x+5=29

4x = 29 - 5

4x = 24

x = 24 : 4

x = 6

2)

3x - 16 = 85 : 17

3x - 16 = 5

3x = 5 + 16

3x = 21

x = 21 : 3

x = 7

3)

6x - 13 = 153 : 9

6x - 13 = 17

6x = 17 + 13

6x = 30

x = 30 : 6

x = 5

4)

8x + 51 = 201 : 3

8x + 51 = 67

8x = 67 - 51

8x = 16

x = 16 : 8

x = 2

5)

46x - 57 = 27 * 3

46x - 57 = 81

46x = 81 + 57

46x = 138

x = 138 : 46

x = 3

6)

19x + 62 = 13 * 15

19x + 62 = 195

19x = 195 - 62

19x = 133

x = 133 : 19

x = 7
