Solve the following system. Then explain what your answer means in the context of the problem.
3x+3y=-15
x+y=-4

  • Algebra II -

    Substitute -4-y for x in the first equation, and solve for y.
    -12 -3y + 3y = -15
    -12 = -15, which is impossible.
    There is no solution to the the pair of equations. They represent a pair of parallel lines that never intersect.
