Answer:

x=28

n=14

Explanation:

x+9=37

Subtract 9 from each side

x+9-9 = 37-9

x = 28

n-5=9

Add 5 to each side

n-5+5 =9+5

n = 14

x + 9 = 37

To solve for x bring 9 to the right side by subtracting 9 to both sides (what you do on one side you must do to the other). Since 9 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.

x + 9 - 9 = 37 - 9

x + 0 = 28

x = 28

Check:

28 + 9 = 37

37 = 37

n - 5 = 9

To solve for n you must add 5 to both sides (what you do on one side you must do to the other). Since 5 is being subtracted, addition (the opposite of subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.

n - 5 + 5 = 9 + 5

n + 0 = 14

n = 14

Check:

14 - 5 = 9

9 = 9

Hope this helped!
