Answer:

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

\(x-y = 48\)

One number x is three less than four times y

\(x= 4y-3\)

now we solve both equations for x and y

Lets solve the first equation for y

\(x-y = 48\)

add y on both sides

\(x= 48+y\)

Now subtract 48 from both sides

\(x-48 = y\)

Replace y in the second equation and solve for x

\(x= 4y-3\)

\(x= 4(x-48)-3\)

\(x=4x - 192 - 3\)

Subtract 4x on both sides

\(-3x=-189\)

Divide by -3

\(x=63\)

So the large number is 63
