Question -3+13x=9. Explain the steps of how you would find the value of x.
What is the value of x?
How do you know that your answer is correct? How can you prove that?

x = 12/13

Step-by-step explanation:

-3 + 13x = 9

Adding 3 to both sides,

13x = 12

Dividing both sides by 13,

x = 12/13

We can prove it by putting the value of x we got in the given equation:

LHS = -3 + 13x

       = -3 + 13 (12/13)

       = -3 + 12

       = 9 = RHS

Hence, proved.
