What are the options of tranformation ??/
Answer:
D
Step-by-step explanation:
Consider the equation:

Use distributive property in both sides:

Separate terms with x into the left part and terms without x into the right part:

Since you get true equality 0 = 0, the equation is true for all real values of x. So, the equation has infinitely many solutions.
7. 3/5 = 4.5/x
3x= 5(4.5)
x = 15/2
8. 6/4 = 9/x
6x= 45
x= 15/2
8. since triangle ABC and ADE are identical,
angle E is also 30 degrees
so angle D = 180-(30+70)=80 degrees
9. 9/3 = x/5
3x = 45
x = 45/3 = 15
