75..... my math teacher would be so proud of me just kidding
-9
9 + 5x = -4x + 63 9 + 9x = 63 9x = 54 9x/9 = 54/9 x = 6
The answer to 7 x 6 plus 9 is 51. You have to multiply 7 by 6 which equals 42 and add 9 onto it which equals 51.

56+19=75
No! It equals 15, but 9-6=3.

(6 x 9) + 6 + 9 = 69

-9
Commutativity.
12 + 16 + 18 + 20 + 9 = 75
The additive property.

-9 + 6 = -3.
9 + 5x = -4x + 63 9 + 9x = 63 9x = 54 9x/9 = 54/9 x = 6
