Answer 2

Let's solve the given equations step by step.

1. Solve for x in the first equation: $x - \frac{5}{3} = 8$.

   Add $\frac{5}{3}$ to both sides to isolate $x$: $x = 8 + \frac{5}{3}$

   To add these fractions, we need a common denominator, which is 3: $x = \frac{24}{3} + \frac{5}{3} = \frac{29}{3}$

2. Solve for x in the second equation: $\frac{6x + 7}{7} = \frac{5x - 3}{8}$.

   Cross-multiply to eliminate the denominators: $8(6x + 7) = 7(5x - 3)$

   Expand and solve for $x$: $48x + 56 = 35x - 21$

   Move all terms involving $x$ to the left side: $48x - 35x = -21 - 56$ $13x = -77$

   Now, divide both sides by 13 to solve for $x$: $x = \frac{-77}{13}$

   We can simplify the fraction by dividing both numerator and denominator by the greatest common divisor (which is 7): $x = \frac{-11}{2}$

So, we have two solutions for $x$: $x_1 = \frac{29}{3}$ $x_2 = \frac{-11}{2}$
