Answer:
factorize form of the equation is
, where 
Step-by-step explanation:
Given Equation:
Adding the terms of 'x' and taking constants on the other side.

The sign of the constant will change on changing the side of it.



So, the value of 'x' is 1
The factorized form of the equation can be made by taking the common value from the equation i.e


Given conditions are :
In 1980's, a typical middle-income household earned= $34,757
In 2009, a similar middle-income household earned= $38,550
And we have to find relative increase in income for these households from 1980 to 2009.
So first we will find the total increase in amounts.

Relative increase = 
= 10.91% or rounding it off we get approx 11%.
Hence, the answer is 11%.
John gets 12, Walt, Matt, and Richie get 4 each
