Find the value of y
------------------------------------------------------------------------
y - 18 = 14
+ 18 + 18
y = 32
------------------------------------------------------------------------
substitute y = 32 into 2 (y + 9)
------------------------------------------------------------------------
2( y + 9 ) = 2 ( 32 + 9 )
2 (y + 9 ) = 2 (41)
2 ( y + 9 ) = 82
------------------------------------
Answer: 82

For this case we have a quadratic equation, 
, of the form 
Where:
We can solve the equation by factoring, that is, we bias two numbers that multiplied give as a result -60 and added as a result 28.
These numbers are:
Then, the factorization is given by:
The roots are:
Answer:
319049
as 100,042 + 98,117 + 120,890 = 319,049
