To find what plus something equals 300, you can represent it mathematically as ( x + y = 300 ), where ( x ) is the known value and ( y ) is the unknown value. For example, if ( x ) is 150, then ( y ) would be 150, since ( 150 + 150 = 300 ). You can replace ( x ) with any number less than 300 to find the corresponding ( y ).
173 plus 127 equals 300
203 + 97 = 300
