One number is four more than three times another number. Find the numbers if the product is 175.
What I have tried: 3n(n+4)= 175 **** How did you come up with that?
---------------
n = a number
The other number is 4 plus 3 times the 1st number, = 3n+4
--------------
n*(3n+4) = 175
Start from there.

let numbers be and
if a number is four more than three times number , then we have:
....eq. 1
if the product is , than we have:
....eq. 2
now, we need to solve the system:
....eq. 1
....eq. 2
_________________________
start with ....eq. 1 and substitute in eq. 2
....eq. 2
......use quadratic formula
solutions:
or
now find
....eq. 1...plug in
or
....eq. 1...plug in
so, we have two pairs, one is and
and another one is and
check:
.....plug in first pair
....true
.....plug in second pair
....round it to whole number
....true
