Respuesta :

Answer: x=4 y=2

Step-by-step explanation:

y = 2x -6, y = -½ x +4

were going to use substitution

y =  2x    -6

(y = -1/2x +4)4 *you are trying to get -1/2 the same as 2x

y =  2x    -6

4y = -2x  +16 *add both equations together

5y = 10 *divide

y=2

2 = 2x -6 *plug y=2 into the equation

+6       +6

8=2x

4=x
