Question

Solve for the following if x = 6: (Hint: substitute 6 for the letter x and work the problem. You will work more with substitution later.) Example: 10x = 10*6 = 60 9. x - 1 ( if x = 3) 10. 12 + x ( if x = 3) 11. 5x - 7 ( if x = 3) 12. 33/x ( if x = 3) 13. 2 + 9x + 12 ( if x = 3)

Answer 1

The values x = 6, the solutions are:

9. 5

10. 18

11. 23

12. 5.5

13. 68

To solve for the following expressions when x = 6, we can simply substitute 6 for the variable x and evaluate the expressions. Here are the solutions:

x - 1 (if x = 6)

= 6 - 1

= 5

12 + x (if x = 6)

= 12 + 6

= 18

5x - 7 (if x = 6)

= 5*6 - 7

= 30 - 7

= 23

33/x (if x = 6)

= 33/6

= 5.5

2 + 9x + 12 (if x = 6)

= 2 + 9*6 + 12

= 2 + 54 + 12

= 68

Therefore, when x = 6, the solutions are:

9. 5

10. 18

11. 23

12. 5.5

13. 68
