the sum of two numbers is 67 if three times the smaller number is subtracted by the larger the result is 7, find two numbers

Respuesta :

Um I think it's 3x7x4=81 or like this 40+20+7=67.
15 and 45. x +y = 67
                 y-3x=7
                 y=7+3x
                 4x+7=67
                4x=60
                x=15
                y+15=67
                y=45
