### No Solutions
Explanation
## Step 1: Convert to Slope-Intercept Form### Convert both equations to the form
to identify slopes and intercepts.- For the first equation
, solve for
:
The slope is
.- For the second equation
, solve for
:
The slope is also
.## Step 2: Compare Slopes and Intercepts### Compare the slopes and
-intercepts of both equations to determine the number of solutions.- Both equations have the same slope (
), indicating they are parallel.- The
-intercepts are different:
for the first equation and
for the second equation.Since the lines are parallel and have different
-intercepts, they do not intersect.
