Method 1)
_______________________
9x / 7 = 18 ;
9x = 18 * 7 ;
Divide EACH SIDE of the equation by "9"; to isolate "x" on one side of the equation; and to solve for "x" ;
_____________________________
9x / 9 = 18 * 7 ;
9
_____________________________
x = 18 * 7 ;
9
_____________________________
The "9" cancels out to a "1" ; and the "18" cancels to a "2" ;
since "18 ÷ 9 = 2" ; and "9 ÷ 9 = 1" ;
so rewrite as:
x = [tex] \frac{2*7}{1} [/tex] = 2 * 7 = 14 .
→ x = 14 .

Method 2)
_________________________________________
9x / 7 = 18 ;
9x = 18 * 7 ;
9x = 126 ;
Divide EACH SIDE of the equation by "9" ; to isolate "x" on one side of the equation; and to solve for "x" ;
______________________________________
9x / 9 = 126 / 9 ;
______________________________________
x = 14 .
