Solve this using substitution:
-x-2y=5
x-4y=19

(3,-4)

Step-by-step explanation:

x-2y=5

x-4y+4y=19+4y

x=19+4y

substitue x

-(19+4y)-2y=5

-19-4y-2y=5

-19-6y=5

-6y=5+19

-6y=24

divide by 6 in both sides

y=-4

find Y now

x=19+4(-4)

x=19-16

x=3

(3,-4)

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

you can't solve x because it is 2 linear equation and you only have one equation
