1. The problem is to solve the equation $2x + 3 - 1 = 5\frac{4}$. 2. First, simplify the left side: $2x + (3 - 1) = 2x + 2$. 3. The right side $5\frac{4}$ is an improper way to write a number. Assuming you mean $5 \times 4 = 20$. 4. So, the equation simplifies to $2x + 2 = 20$. 5. Subtract 2 from both sides: $2x = 20 - 2 = 18$. 6. Divide both sides by 2: $x = \frac{18}{2} = 9$. 7. Therefore, the solution is $x = 9$.
