Answer

\( w = \frac{19}{18} \)

Solution

To solve for \( w \) in the equation: \[ -\frac{3}{2} w + \frac{1}{4} = -\frac{4}{3} \] **Step 1: Isolate the term containing \( w \).** Subtract \(\frac{1}{4}\) from both sides: \[ -\frac{3}{2} w = -\frac{4}{3} - \frac{1}{4} \] **Step 2: Simplify the right side by finding a common denominator.** The common denominator for \(-\frac{4}{3}\) and \(-\frac{1}{4}\) is 12: \[ -\frac{4}{3} = -\frac{16}{12} \quad \text{and} \quad -\frac{1}{4} = -\frac{3}{12} \] So, \[ -\frac{3}{2} w = -\frac{16}{12} - \frac{3}{12} = -\frac{19}{12} \] **Step 3: Solve for \( w \).** Multiply both sides by \(-\frac{2}{3}\) to isolate \( w \): \[ w = \left(-\frac{19}{12}\right) \times \left(-\frac{2}{3}\right) = \frac{38}{36} \] **Step 4: Simplify the fraction.** \[ \frac{38}{36} = \frac{19}{18} \] **Final Answer:** \[ w = \frac{19}{18} \]

The Deep Dive

To solve for \( w \) in the equation \[ -\frac{3}{2} w + \frac{1}{4} = -\frac{4}{3}, \] first, we’ll isolate \( w \). Start by moving \( \frac{1}{4} \) to the right side: \[ -\frac{3}{2} w = -\frac{4}{3} - \frac{1}{4}. \] Next, we need a common denominator to combine the fractions on the right. The least common multiple of 3 and 4 is 12. Thus, we convert the fractions: \[ -\frac{4}{3} = -\frac{16}{12}, \quad \frac{1}{4} = \frac{3}{12}. \] Now substituting back into the equation: \[ -\frac{3}{2} w = -\frac{16}{12} - \frac{3}{12} = -\frac{19}{12}. \] Now, divide both sides by \(-\frac{3}{2}\): \[ w = \frac{-\frac{19}{12}}{-\frac{3}{2}}. \] When dividing fractions, you can multiply by the reciprocal: \[ w = \frac{19}{12} \cdot \frac{2}{3} = \frac{19 \cdot 2}{12 \cdot 3} = \frac{38}{36}. \] Now, simplify \( \frac{38}{36} \): \[ w = \frac{19}{18}. \] Thus, the solution for \( w \) is \[ \boxed{\frac{19}{18}}. \]
