Explain why the two equations below have the same solutions. x + 3y = - 1 - 2x - 6y = 2

X + 3y = - 1

-2x - 6y = 2

These two equations have the same solution because we can see that they are equivalent.

One way to find out is this:-

Since x has a + 1 next to it, and the other equation has a (-2) next to the x, we can multiply everything on the first equation by 2 to see if they are equivalent.

x+3y = - 1

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

-2x + (-6y) = 2

-2x-6y=2

Now we know that both of these equations have the same solution.
