Question

1. What is the solution to the system of equations?
3x - 6y = -12
x - 2y = -8
(a) Use the substitution method to justify that the given system of equations has no solution.
(b) What do you know about the two lines in this system of equations?

1 Answer

  • Solution to the 1st equation: x
    3x-6y=-12
    3(x-2y)=-12
    x-2y=-4
    →x=2y-4

    Solution to the 1st equation: y
    3x-6y=-12
    3(x-2y)=-12
    x-2y=-4
    -2y=-4-x
    →y=-4-x/2
