Step-by-step explanation:
Let the sum of rupee be x
no of boys be y
then each boy get x/y
now if the no of boys increased by 10 each boy get x/(y+10) = (x/y)-1 => x/(y+10) = (x-y)/y .........(1)
now case 2nd if no of boys decrease by 15 each boy get x/(y-15)= (x/y) +3 => x/(y-15) = (x+3y)/y ...........(2)
The statistic about college graduates which is not true is that C. they can earn nearly double the income of high school graduates.
They cannot earn that much really - even though they have a college degree, there are many jobs that don't require a degree which also pay a lot.
Given Equations
- 5x+3y=8--(1)
- 4x+7y=34--(2)
Let it has solution (x,y)
Add both


It will also have same solution (x,y)
8+.90+.07
This the answer because you have to make it as an addition way.
Hope I helped.
