Solve the linear system of equations using addition. Graph the equations to verify your solution. required.
zhenek [66]
<h3>Answer:</h3>

infinite solutions

<h3>Step-by-step explanation:</h3>

Add the two equations.

... (-4x) + (y) = (y +3) +(-4x -3)

Add 4x -y to both sides.

... -4x +y +4x -y = -4x +y +4x -y

... 0 = 0 . . . . . true for all values of x (or y)

Both equations describe the same line.

_____

The graph shows the first equation as a red line. The second equation is shown using a "blue dot" texture, so you can see it overlays the red line.
