One number is three less than four times another.. if their difference is 48, what is the larger number

the large number is 63

Step-by-step explanation:

One number is three less than four times another.. if their difference is 48, what is the larger number.

Let the larger number is x  and smaller number is y

One number x is three less than four times y

now we solve both equations for x and y

Lets solve the first equation for y

add y on both sides

Now subtract 48 from both sides

Replace y in the second equation and solve for x

Subtract 4x on both sides

Divide by -3

So the large number is 63

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
