I hope u understand this answer

Step-by-step explanation:

7+9d=7d+3

9d+7=7d+3

9d+7-7=7d+3-7

by subtracting the number

9d=7d-4

subtracting 7d from both sides of the equation

9d=7d-4

9d-7d=7d-4-7d

now simplyfi..combine like terms

2d=-4

Divide both sides of the equation by the same term

2d=-4

2d/2=-4/2

now cancel terms that are in both the numerator and denominator

Divide the number

d=-2
