Question

The difference of 9d and 4d is -100

Answer 1

Hello!

Answer:

`\Large \boxed{\sf d = -20}`

Explanation:

◼ We want to solve this equation:

`\sf 9d - 4d =- 100`

◼ Simplify the left side:

`\sf 5d = -100`

◼ Divide both sides by 5:

`\sf (5d)/(5) = (-100)/(5)`

◼ Simplify both sides:

`\boxed{\sf d = -20}`

Conclusion:

The solution of the equation the difference of 9d and 4d is -100 is -20.

Answer 2

d = - 20

Explanation:

the difference of 9d and 4d = 9d - 4d

given the difference is - 100 , then

9d - 4d = - 100

5d = - 100 ( divide both sides by 5 )

d = - 20
