Answer:
-3y +7x = 14
Step-by-step explanation:
The inverse relation is found by swapping the x- and y-variables. The relation that is the inverse of ...
-3x +7y = 14 . . . . given relation
is
-3y +7x = 14 . . . . inverse relation
Step-by-step explanation:
Let the two numbers be 20x and 10x
Then by the question,
20x + 10x = 300
or, 30x = 300
or, x = 300/ 30
x = 10
Now the larger number
20x = 20* 10 = 200.
