Hi Friend,

; is not the operator or you may get type error

I am going to solve it considering + as well as -

first + i use in equation  20 + 5x + 7 = 107

5x + 27 = 107

 5x = 107 - 27 = 80

5x = 80

x = 16

- use in equation

20 - 5x + 7 = 107

27 - 5x = 107

5x = 107 + 27

5x = 134

x = 26.4

Hope you get the answer

Please best my answer.

Thanks
