Can someone me pls? algebra is hard for me and i don't understand it.
1. solve the system. show your work using graphing or substitution or elimination. check your answer by showing your solution works in both original equations. y = 2x -6 y = -½ x +4
show work

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

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
