Answer:
Step-by-step explanation:
y = 5x + 4
-5x + y = 4 ----------------------(i)
3x + 2y = 20 --------------------(ii)
Multiply equation (i) by (-2)
(i)* (-2) 10x - 2y = -8
(ii) <u>3x + 2y = 20</u> { Now add this two equations}
13x = 12 { -2y and 2y got eliminated}
x = 12/13
Plug in value of x in (i)
-5*12/13 + y = 4
-60/13 + y = 4
y = 4 + 60/13
![y=\frac{4*13}{1*13}+\frac{60}{13}\\\\=\frac{52}{13}+\frac{60}{13}\\\\=\frac{112}{13}\\\\=8\frac{8}{13}y=](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B4%2A13%7D%7B1%2A13%7D%2B%5Cfrac%7B60%7D%7B13%7D%5C%5C%5C%5C%3D%5Cfrac%7B52%7D%7B13%7D%2B%5Cfrac%7B60%7D%7B13%7D%5C%5C%5C%5C%3D%5Cfrac%7B112%7D%7B13%7D%5C%5C%5C%5C%3D8%5Cfrac%7B8%7D%7B13%7Dy%3D)
Answer:
False
Step-by-step explanation:
The point (-1, 4) is not touched by the line 4x+5y=6 so there for it is not a solution.
Answer:
It will not be very helpful to use this point because it lies on the x-axis. Which doesn't show what area to shade.
