-7d = 50 + 2d
-9d = 50
d = -50/9
Or about -5.6
The commutative property.
2 - 7d = -75 7d = 2 - (-75) 7d = 77 d = 77/7 d = 11
Which property is illustrated in this problem? (associative, distributive, identity, or commutative) 7d + 3 = 3 + 7d

3c-d
7d - 12 + 2d + 3 = 18Group the like terms for d on the left side. Move the integers to the right side remembering to reverse their signs (positive/negative)7d + 2d = 18 + 12 - 3Which becomes:9d = 27Divide each side by 9:d = 3

It is: 2d+9
The commutative property.
Expressed algebraically, d + 7d = 8d.

15d + 7 = 7d + 15 is an equation in one variable, d.
Commutativity.
1. 7d-13=3d+72. 7d-20=3d3. -20=-4d4. d=55. Check your answer:7*5-13=22, 3*5+7=22D equals 5
5de+9e+7d+10e=5de+7d+19e
To solve the equation 6d - 3d + 2d = 35, we first combine like terms on the left side. This gives us 5d + 2d = 35. Combining like terms further, we get 7d = 35. To find the value of the unknown variable "d," we divide both sides by 7, resulting in d = 5.
2 - 7d = -75 7d = 2 - (-75) 7d = 77 d = 77/7 d = 11
