To solve the equation \( \frac{3m + 5}{4} - \frac{3m}{4} = -2 \), we first simplify the left side.
- Combine the fractions on the left side:
\[ \frac{3m + 5 - 3m}{4} = -2 \]
This simplifies to:
\[ \frac{5}{4} = -2 \]
- To eliminate the fraction, multiply both sides by 4:
\[ 5 = -2 \times 4 \]
This results in:
\[ 5 = -8 \]
This equation is clearly false, hence it implies there is no real value of \( m \) that can satisfy the original equation.
Thus, the equation has no solution.
