Answer:
x = (9/24)
Step-by-step explanation:
Step one: Subtract 10x from both sides.
24x - 18 = -9
Step 2: Add 18 to both sides.
24x = 9
Step 3: Divide it all by 24.
x = (9/24)
Cross multiplication will help find the value of x

9*2=18
3*z=3z
Now we have :
3z=18
Divide both sides by 3 to isolate z
Final answer: z=6
That's impossible to say. The radius of a square is meaningless.
