Answer 2

It seems like you've provided an equation involving fractions and an expression with variables. I'll help you break down the equation and solve for the variable "x."

The equation you've given is: $\frac{1}{25} + \frac{8}{75} = \frac{4}{7} \cdot (3x - 5)$

Let's start by simplifying the fractions on the left side of the equation: $\frac{1}{25} + \frac{8}{75} = \frac{3}{75} + \frac{8}{75} = \frac{11}{75}$

Now the equation becomes: $\frac{11}{75} = \frac{4}{7} \cdot (3x - 5)$

To solve for "x," you can isolate the variable by dividing both sides of the equation by $\frac{4}{7}$: $(3x - 5) = \frac{11}{75} \div \frac{4}{7}$

Dividing by a fraction is the same as multiplying by its reciprocal: $(3x - 5) = \frac{11}{75} \cdot \frac{7}{4}$

Now, perform the multiplication on the right side: $(3x - 5) = \frac{77}{300}$

Finally, solve for "x" by isolating the variable: $3x = \frac{77}{300} + 5$ $3x = \frac{77 + 1500}{300}$ $3x = \frac{1577}{300}$

Now divide both sides by 3 to solve for "x": $x = \frac{1577}{900}$

So, the solution for the equation is $x = \frac{1577}{900}$, which is an approximate decimal value of $x \approx 1.7522$.
