Okay so you need to get the y by itself
2x - 4y = 20
subtract the 2x over
-4y = -2x + 20
divide everything by -4
y = 1/2x - 5 <------- this is your answer
I dont knwo why i have to type a bunch the anser in 366

<u>j</u><u> </u><u>is</u><u> </u><u>-</u><u>1</u><u>8</u>
Step-by-step explanation:
![- 108pi = 6pij \\ - 108 = 6j \\ j = - 18](https://tex.z-dn.net/?f=%20-%20108pi%20%3D%206pij%20%5C%5C%20%20-%20108%20%3D%206j%20%5C%5C%20j%20%3D%20%20-%2018)
Hello,
Assume Ax+By+Cz+D=0 the plane 's equation.
p=(0,0,0)==>A*0+B*0+C*0+D=0==>D=0
q=(0,1,0)==>A*0+B*1+C*0+0=0==>B=0
r=(1,2,3)==>A*1+0*2+C*3+0=0==>A=-3C
Let C=1==>A=-3
An equation of the plane is -3x+z=0
