Question

How many solutions does this linear system have?

Answer 1

it is no solution, bc the answer is (0,0)

Answer 2

one solution (0,-1)

Explanation:

`y=5x-1`

`-15x-3y=3`

LEts solve for x and y, Substitute 5x-1 for y in second equation

`-15x-3y=3`

`-15x-3(5x-1)=3`

`-15x-15x+3=3`

Combine like terms

`-30x+3=3`

Subtract 3 on both sides

`-30x=0`

Divide both sides by -30

`x=0`

Now plug in 0 for x in first equation

`y=5x-1`

`y=5(0)-1=-1`

So one solution (0,-1)
