Given:
____________________________________________________
2 / (9x) = 4 / 7 ; solve for "x" ;
____________________________________________________
Cross-multiply:
→ (9x)*4 = 2 * 7 ;
→ 36x = 14 ;
Divide each side of the equation by "36" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
→ 36x / 36 = 14 / 36 ;
x = 14/ 36 ;
→ x = 14/36 = (14÷2) / (36÷2) = 7/18 ;

The answer is: " [tex] \frac{7}{18} [/tex]" ;
→ which is: Answer choice: [C]: " [tex] \frac{7}{18} [/tex]" .
