Question

For the systems of linear equation in question: 0.2x+0.4y=1.7 and 8.3x-6.3y=-4.3. Determine how many solutions exist, use either elimination or substitution to find the solutions (if any), graph the two lines, labeling the x-intercepts, y-intercepts, and points of intersection.

Answer 1

I really dislike computations, especially ones with decimal points in them so
