To solve the equation $\frac{4 y-6}{4}+\frac{13}{8}=\frac{8 y+1}{8}$, we can follow these steps:
Find a common denominator for all the fractions involved.
Combine the fractions on the left-hand side.
Simplify the equation to isolate the variable \( y \).
Step 1: Find a common denominator
To solve the equation \(\frac{4y-6}{4} + \frac{13}{8} = \frac{8y+1}{8}\), we first find a common denominator for all the fractions. The common denominator for 4 and 8 is 8.
Step 2: Rewrite the equation with a common denominator
Rewrite each term with the common denominator:
\[
\frac{4y-6}{4} = \frac{2(4y-6)}{8} = \frac{8y-12}{8}
\]
So the equation becomes:
\[
\frac{8y-12}{8} + \frac{13}{8} = \frac{8y+1}{8}
\]
Step 3: Combine the fractions on the left-hand side
Combine the fractions on the left-hand side:
\[
\frac{8y-12 + 13}{8} = \frac{8y+1}{8}
\]
Simplify the numerator:
\[
\frac{8y + 1}{8} = \frac{8y + 1}{8}
\]
Step 4: Simplify the equation
Since both sides of the equation are equal, the equation holds for all values of \( y \). This means that the equation is an identity and there are infinitely many solutions.
Final Answer
\[
\boxed{\text{The equation is an identity and has infinitely many solutions.}}
