To find the number of solutions to the system of equations given, we can use the method of substitution or elimination.
Method 1: Substitution
Let's solve the first equation for y:
y = 6x + 2
Now substitute this expression for y in the second equation:
3(6x + 2) - 18x = 12
18x + 6 - 18x = 12
6 = 12
This equation is not true, indicating that there is no solution to the system of equations. Therefore, there are no solutions.
Method 2: Elimination
Let's multiply the first equation by 3 to match the coefficient of y in the second equation:
3y = 18x + 6
Now we have:
3y - 18x = 12
Comparing this equation with the second equation, we see that they are identical. This means that the two equations represent the same line. Since they are the same line, they will intersect at infinitely many points, and thus have infinitely many solutions.
In summary:
- Method 1 (Substitution): No solutions
- Method 2 (Elimination): Infinitely many solutions

You're welcome! It's indeed interesting how systems of equations can have different types of solutions. In this case, the two equations represent the same line, so they intersect at every point on that line, resulting in infinitely many solutions. It's always good to check the nature of the system to determine the number and type of solutions. If you have any more questions, feel free to ask!
