# How do you solve the system of equations y=-3x-1 and 3x+y=-1?

Sep 23, 2015

There are innumerable number of solutions.

#### Explanation:

$y = - 3 x - 1$ -----------------------(1)
$3 x + y = - 1$ ------------------------(2)

Both the equations are one and the same.
Solve equation (2) for $y$

$y = - 3 x - 1$ -------------------(2)

The second line will coincide with the first one.
Hence, there are innumerable number of solutions.
