You can put this solution on YOUR website!
let the number be x
other number = 3x+28
4(3x+28)-4x=232
12x+112-4x=232
8x+112=232
8x=232-112
8x=120
/8
x=15
one number is 15
other number is 3x+28
3*15+28
73
the numbers are 15 & 73

I can see why you have trouble. It's hard to read.
Call the numbers +a+ and +b+
given:
(1) +a+=+3b+%2B+28+
From this data, you can see that +a+ is the larger number
You can use this fact in the next equation
(2) +4a+-+4b+=+232+
--------------------
(1) +a+-+3b+=+28+
and
Divide both sides of (2) by 4
(2) +a+-+b+=+58+
Subtract (1) from (2)
(2) +a+-+b+=+58+
(1) +-a+%2B+3b+=+-28+
+2b+=+30+
+b+=+15+
and, since
(2) +a+-+b+=+58+
(2) +a+-+15+=+58+
(2) +a+=+58+%2B+15+
(2) +a+=+73+
The numbers are 73 and 15
check:
(1) +a+=+3b+%2B+28+
(1) +73+=+3%2A15+%2B+28+
(1) +73+=+45+%2B+28+
(1) +73+=+73+
and
(2) +4a+-+4b+=+232+
(2) +4%2A%28+a+-+b+%29+=+232+
(2) +4%2A%28+73+-+15+%29+=+232+
(2) +4%2A58+=+232+
(2) +232+=+232+
OK
