Question 82471: Does this system of equations 2x+y= -4 and 5x+3y= -6 have 1 solution, no solutions or infinetly many solutions? Answer by checkley75(3666) (Show Source):
You can put this solution on YOUR website! USING A GRAPHING METHOD TO SOLVCE WE GET
2X+Y=-4, Y=-2X-4
5X+3Y=-6, 3Y=-5X-6, Y=-5X/3-6/3, Y=-5X/3-2
NOW WE PLOT: (graph 300x200 pixels, x from -8 to 5, y from -10 to 12, y = -2x -4 and y = -5x/3 -2).
FROM THIS GRAPH IT APPEARS TO HAVE 1 SOLUTION (-6,8).
