Follow the steps given, make a conjecture then prove your conjecture deductively:



1.  Think of a number. ( i picked 2 pls)      

Let x = the number

 

2.  Multiply the number by 5

Now we have 5x



3.  Add 17 to the result in Step 2.

Now we have 5x+17



4.  Triple the result in Step 3.

Now we have 3(5x+17) or 15x+51



5.  Reduce the result in Step 4 by 6

Now we have 15x+45



6.  Divide the result in Step 5 by 5

Now we have 3x+9



7.  Subtract 9 from the result in Step 6.

Now we have 3x



You are left with three times the original number.
