# One number is 28 more than three times another number. If each number were multiplied by 4, their difference would be 232. What are the numbers?

We'll note the numbers as x and y.

We'll put as x the number that is 28 more than three times y.

We'll write the sentence mathematically:

x = 28 + 3y (1)

Now, we'll write mathematically the other constraint from enunciation:

4(x - y) = 232

We'll divide by 4;

x - y = 58

x = 58 + y (2)

We'll put (1) = (2):

28 + 3y = 58 + y

We'll isolate y to the left side:

3y - y = 58 - 28

2y = 30

y = 15

x = 58 + y

x = 58 + 15

x = 73

**The numbers are: x = 73 and y = 15.**

Let the two numbers be x and y. Then x = 28+3y by first condition.

When each number is multiplied by 4, then their difference is 4(x-y) which is said to be 232.

So 4(x-y) = 232. We substitute x= 28+3y in 4(x-y) = 232.:

4{28+3y-y) =232.

We divide by 4:

28+2y = 232/4 = 58.

2y = 58-28 = 30.

So y = 30/2 = 15.

So x= 28+3y = 28+3*15 = 73.

Therefore the two numbers are 73 and 15.

Therefore x= 73 and y = 15.
