Answer:

To solve the system of equations, we can use Cramer’s Rule. However, to write each equation in slope-intercept form, we need to rearrange them so that y is isolated on one side of the equation.

The first equation is:

2x+y=−3

Subtracting 2x from both sides, we get:

y=−2x−3

Therefore, the slope-intercept form of the first equation is:

y=−2x−3

The second equation is:

−2y=6+4x

Dividing both sides by -2, we get:

y=−2x−3

Therefore, the slope-intercept form of the second equation is:

y=−2x−3

As you can see, both equations have the same slope-intercept form. This means that they are equivalent and represent the same line. Therefore, there are infinitely many solutions to this system of equations.
