For each ordered pair, determine whether it is a solution to the system of equations. y=-3x-4
9x+2y=-5

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

If you have the following equation, 2/3x+5/6-x=2-3/4x what would you multiply each term by to get rid of all the fractions

Four individuals pool money together to start a new business and agree to split the profits equally. n invests $6,000, x invests $2,000, y invests $8,000 and z invests $4,000. if the profits for the first month were $100,000, y receives than if the profits were divided in proportion to how much they invested.
