Answer:

x = [tex]\frac{16}{41}[/tex]

y =[tex]\frac{102}{41}[/tex]

Step-by-step explanation:

To use elimination I need either the x terms to be inverses of each other or the y terms to be inverses of each other.  There are a number of ways to do this.  I am going to focus on the y's.  If I multiple the first equation through by 5 and the second equation through by 3.  I will make equivalent equations that will allow the y terms to be eliminated.

14x - 3y = -2

5(14x - 3y) =5(-2)

70x - 15y = -10

4x + 5y = 14

3(4x + 5y) = 3(14)

12x +15y =42

Add together the 2 bold equations above

70x - 15y = -10

12x + 15y = 42

82x          = 32  Divide both sides by 82

x = [tex]\frac{32}{82}[/tex] = [tex]\frac{16}{41}[/tex]

Plug this in either equation to solve for y

y = [tex]\frac{102}{41}[/tex]
