The equation given in the question is definitely solvable for finding the value of the unknown variable "x". There is only one unknown variable and one equation.The equation given in the question is
10/8 = (x - 10)/10
(10 * 10)/8 = (x - 10)
100 = 8(x - 10)
100 = 8x - 80
Reversing the two sides, we can write the equation as
8x = 100 + 80
8x = 180
x = 180/8
  = 22.5
So the value of the unknown variable comes out to be equal to 22.5. I hope the procedure is clear enough for you to understand.

Use PEMDAS:

10/8= x- 10/10
⇒ 5/4= x- 1 
⇒ x= 5/4+ 1
⇒ x= 5/4+ 4/4
⇒ x= 9/4
⇒ x= 2 1/4

Final answer: x= 2 1/4~
