Question

Given the system of equations, match the following items.

x + 3y = 5
x - 3y = -1


{5 3}
{-1 -3}


{1 5}
{1 -1}


{1 3}
{1 -3}

Answer 1

Just add the 2 equations, which cancels out the 3y term. That will give you x, then plug it into either equation to find y. It's recommended that you check both values in the other equation to prove your solution is correct.

Answer 2

is the first set an x, y or sytem determinant?
