Answer
### Infinitely Many Solutions
Explanation
## Step 1: Convert Equations to Slope-Intercept Form### The first equation is
. Solving for
, we get
. The second equation is
. Solving for
, we get
.## Step 2: Compare Slopes and Intercepts### Both equations have the same slope
and the same
-intercept
. This means the lines are identical.## Step 3: Determine the Number of Solutions### Since the lines are identical, they overlap completely, indicating that there are infinitely many solutions.
