Sagot :
Let 7x and 4x be the 2 numbers we were looking for.
With that , our equation for this problem base on the given was
7x - 4x = 48
then we solve for x
3x = 48
x = 16
Since we were looking for the sum of the numbers , our equation for that will be
Sum= 7x + 4x
then substitite the values we got
Sum = 7(16) + 4(16) = 176
