The answer is: " x = 5 " .
_______________________________________________
Note the following:
_______________________________________________
2/4 = 1/2 ;
1/2 = (1*5) / (2*5) = 5/10 ;
2/4 = 1/2 = 5 / 10 .
or: 2/4 = 1/2 = 0.5 = 5/ 10 .
The answer: " x = 5 " .
___________________
Or: x/ 10 = 2/4 ;
Cross-multiply:
4x = (2)(10) ;
4x = 20 ;
Divide each side by "4" ;
4x / 4 = 20/4 ;
" x = 5 " ;
_____________________
Or: x/10 = 2/4 ;
Note: "2/4 = 1/2" ; so rewrite as:
x/10 = 1/2 ; and cross-multiply:
2x = (10)(1) ;
2x = 10 ;
Divide each side of the equation by "2" ;
2x / 2 = 10 / 2 ;
" x = 5 " .

Because 7x equals 7x. Its not less than it if it equals it.
