ANSWER: ( 0.75 , 2 )

EXPLANATION:
To find the system of solutions, solve the 2 equations.
(1) Find what you can multiply with to get the same number in the second equation.
(2) Multiply equation by -2
(3) New equation:
-4x - 2y = -6
3x + 2y = 8
(4) Add both equations
(5) New equation:
7y = 14
(6) Divide both sides by 7
(7) New equation:
Y = 2
-
Now find X
(1) Substitute y with a equation
(2) 3x + 2 (2) = 8
(3) 3x + 4 = 8
(4) Subtract 4 both sides
(5) 3x = 4
(6) Divide 3 both sides
(7) x = 0.75
