Question: Solve for $x$ and simplify the answer fully. $$\frac{x - 8}{x - 2} = \frac{7}{8}$$
1. **State the problem:** Solve the equation $$\frac{x - 8}{x - 2} = \frac{7}{8}$$ for $x$ and simplify fully. 2. **Use the cross-multiplication formula:** When two fractions are equal, their cross products are equal: $$ (x - 8) \times 8 = (x - 2) \times 7 $$ 3. **Multiply both sides:** $$ 8(x - 8) = 7(x - 2) $$ 4. **Distribute the constants:** $$ 8x - 64 = 7x - 14 $$ 5. **Isolate $x$ terms on one side and constants on the other:** $$ 8x - 7x = -14 + 64 $$ 6. **Simplify both sides:** $$ x = 50 $$ 7. **Check for restrictions:** The denominator $x - 2$ cannot be zero, so $x \neq 2$. Since $x = 50$ does not violate this, it is valid. **Final answer:** $$ x = 50 $$
