Question

Solve the following system using the elimination method:
2x + 5y = 10
-4x - 10y = -20

Answer 1

first divide the second equation by two

Answer 2

that would make
2x+5y=10
-2x-5y=-10

Answer 3

Seems it will be 0 = 0, so you have infinite many solutions.

Answer 4

the you add that would result in 0

Answer 5

is it dependent or inconsistent

Answer 6

consistent and dependent

Answer 7

since they are the same line and have infinite solutions

Answer 8

so theres no coordinate

Answer 9

the two equations are the same

Answer 10

ok

Answer 11

how about this one
Solve the following system using the elimination method:
-5x + 2y = 1
6x + 4y = -14
