Solve Linear System F166F5
1. **State the problem:** Solve the system of equations:
$$\frac{1}{2}x + \frac{1}{3}y = 4$$
$$\frac{1}{4}x - \frac{1}{6}y = 1$$
2. **Rewrite the equations to clear denominators:**
Multiply the first equation by 6 (LCM of 2 and 3):
$$6 \times \left(\frac{1}{2}x + \frac{1}{3}y\right) = 6 \times 4$$
$$3x + 2y = 24$$
Multiply the second equation by 12 (LCM of 4 and 6):
$$12 \times \left(\frac{1}{4}x - \frac{1}{6}y\right) = 12 \times 1$$
$$3x - 2y = 12$$
3. **Add the two new equations to eliminate $y$:**
$$(3x + 2y) + (3x - 2y) = 24 + 12$$
$$6x = 36$$
4. **Solve for $x$:**
$$x = \frac{36}{6} = 6$$
5. **Substitute $x=6$ into one of the simplified equations to find $y$:**
Using $3x + 2y = 24$:
$$3(6) + 2y = 24$$
$$18 + 2y = 24$$
$$2y = 24 - 18 = 6$$
$$y = \frac{6}{2} = 3$$
6. **Final answer:**
$$x = 6, \quad y = 3$$
