In this problem, we are finding two unknowns. So we shall
Let x=the greater number
y=the smaller number
The difference of the numbers is 12.
So, x-y=12
From which, x=y+12
Two fifths of the greater number is six more than one third of the lesser number
So,
To eliminate the fractions, let us multiply both sides by 15.
~~~~~~
But, x=y+12, so,
~~~
Subtracting 30 both sides,
~
~~~~
Again, x=y+12, so,
x=y+12
x=-42+12
x=-30
Therefore, the two numbers are -30 and -42!
