Linear Equations 12B936
1. **State the problem:** We are given two linear equations:
$$y = 2kx + 3$$
and
$$3y - 9 = 18x$$
We want to analyze these equations, possibly to find the value of $k$ such that the two lines are equivalent or to find their intersection.
2. **Rewrite the second equation in slope-intercept form:**
Start with
$$3y - 9 = 18x$$
Add 9 to both sides:
$$3y = 18x + 9$$
Divide both sides by 3:
$$y = 6x + 3$$
3. **Compare the two equations:**
First equation: $$y = 2kx + 3$$
Second equation: $$y = 6x + 3$$
For the two lines to be the same, their slopes and intercepts must be equal.
4. **Set slopes equal:**
$$2k = 6$$
Solve for $k$:
$$k = \frac{6}{2} = 3$$
5. **Conclusion:**
The value of $k$ that makes the two lines identical is $k = 3$.
**Final answer:**
$$k = 3$$
