Answer 2

Answer: Mark as brainliest if it is helpful

Step-by-step explanation: 2 times means *2.

The equation is : 2(x+7) = 13. Solution :

  2 (x+7) = 13

  x+7 = 13/2

  x = 13/2 - 7. By taking LCM we get denominator 2.

  x  =  (13 - 14)/2

  x = -1/2

                          (Or we can do like this)

2(x+7) = 13

 (2*x) + (2*7) = 13

 2x = 13 -14

  2x = -1

   x = -1/2

So 'x' = -1/2.
