Question

Solve by using elimination
y=2x-1
2x-y-1=0

Answer 1

They are the same equations!!!!

Answer 2

look if you move the x and y to the lefthand side and the constant to the right hand side then you will see that they are the same equations

Answer 3

y = 2x - 1
2x - y - 1 = 0

y = 2x - 1
-y = -2x + 1

y = 2x - 1
y = 2x - 1

y will vary according to the value of x ~ without further information they could be anything.



ANSWER

this system has infinitely many solutions

Answer 4

Solve y=2x-1
2x-y-1=0
