ANSWER

The solution to the system is


x=5,y=-5



EXPLANATION

The system of equations are:


3x + 2y - 5 = 0 - - (1)

and


x = y + 10 - - (2)



We put equation (2) in to equation (1) to get,


3(y + 10) + 2y - 5 = 0

We expand the parenthesis to obtain,



3y + 30 + 2y - 5 = 0

We group like terms to obtain,


3y + 2y + 30 - 5 = 0




5y + 25 = 0


This implies that,



5y = - 25

We divide through by 5 to get



y = - 5


We substitute the value of y in to equation (1) to get,

3x + 2( -5 ) - 5 = 0



3x - 10- 5 = 0



This implies that


3x = 15
We divide both side by 3 to get,


x = 5
