Explanation:

To solve:

* = 135 .

→ The "100" cancels out to a "20" ; and the "45" cancels out to a "9" ;

→ {since: "100 ÷ 5 = 20" ; and since: "45 ÷ 5 = 9" } ;

→ So; we rewrite as:

* = 135 ;

→ Note: " " = 90 ;

→ So; we rewrite as:

* 9 = 135 ;

→ Now. divide each side of the equation by "9" ; to further simplify the problem; as follows:

{ ( * 9 ) / 9 ) } = {135 / 9 } ;

to get:

= 15 ;

Now, multiply EACH SIDE of the equation by "20" ;

→ to isolate "x" on one side of the equation; & to solve for "x" ;

→ 20 * {} = 15 * 20 ;

to get:

→ x = 300 .
