Question

solve the following equation 2x+7=13 i know the answer is 3 but there is written that answer is 2​

Answer 1

2x+7=13

13=2X+7

13-7=2x

13-7=6

6=2x

6/2=2x/2

=3

x=3

Answer 2

Answer:

Step-by-step explanation:

2x + 7 = 13

so  2x = 13 - 7

     2x =  6

       x  = 6/2

so  x    = 3

therefore the value of x is 3 .

x cannot be 2 as when we put x = 2

the equation becomes   2* 2 + 7 that is not equal to 13
