1. Does the system of linear equations shown below have a solution? Explain.

The figure above shows the lengths of thesides of a rectangle in cm. find the valuesof x and y and then the area of the rectangle.sides: top= 3x - yleft= 3y + 4bottom= 2x + yright= 2x - 3 use both methods, elimination and substitution, if possible.

If 90° < θ < 180° and cotθ = -1/3, then cscθ =
