13x=9+3

13x=12

x=12/13

-3+13×12/13=9

Answer:

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.
