Ответ:
Subtract both equations
x + 2y = 2
x - 4y = 14
6y = -12, y = -2
Plug in y = -2 in any equation
x + 2(-2) = 2
x - 4 = 2, x = 6
Solution: x = 6, y = -2
Or coordinate (6,-2)
Ответ:
|x-8|= 6
Step-by-step explanation:
We have 2 and 14. (i suggest putting these on a number line for vIsUaL purposes) but we have to find the midpoint and the distance from midpoint.
Midpoint: 8
Distance: 6
Now we put into equation and get:
|x-8|= 6
Hope this helped and if this is wrong try |x-6|=8 just incase ;)
