Answer: d = -6

Explanation:

4*d+7-(-17)=0

Step by step solution :

Step 1 :

Pulling out like terms :

1.1 Pull out like factors :

4d + 24 = 4 • (d + 6)

Step 2 :

Equations which are never true :

2.1 Solve : 4 = 0

Solving a Single Variable Equation :

2.2 Solve : d+6 = 0

Subtract 6 from both sides of the equation :

d = -6

d = -6

hope this helps you :)
