Question

If you know any of these please help!

Answer 1

5: 13

6: 7

7: 26

8: 18

9: x=11 , y=3

Explanation:

5:

9x + 2 = 119

9x = 117

x = 13

6:

12x - 8 + 104 = 180

12x - 8 = 76

12x = 84

x = 7

7:

5x + 7 = 8x - 71

3x = 78

x = 26

8:

7x - 61 = 4x - 7

3x = 54

x = 18

9:

9x + 25 = 13x - 19

4x = 44

x = 11

13(11) - 19 + 17y - 5 = 180

143 - 24 + 17y = 180

119 + 17y = 180

17y = 61

y = 3
