## Step 1The given system of equations is:\(y=-2(x+3)\) and
.## Step 2We can rewrite the first equation in the form
, where
is the slope and
is the y-intercept. The equation becomes
.## Step 3Now, we can compare the two equations. Both equations have the same slope, which is -2. However, the y-intercepts are different. The y-intercept of the first equation is -6, while the y-intercept of the second equation is 3.## Step 4Since the lines have the same slope but different y-intercepts, they are parallel and will never intersect. Therefore, the system of equations has no solution.
