d. solve for d: 7d - 4 = 10
d. solve for d: 7d - 4 = 10
Answer
Explanation:
Step1: Isolate the term with the variable
Add 4 to both sides of the equation (7d - 4=10). $$7d-4 + 4=10 + 4$$ $$7d=14$$
Step2: Solve for (d)
Divide both sides of the equation (7d = 14) by 7. $$\frac{7d}{7}=\frac{14}{7}$$ $$d = 2$$
Answer:
(d = 2)
