The correct Answer is:
To determine how many solutions the system of equations has, we can follow these steps: ### Step 1: Write the first equation in standard form. The first equation is: \[ 4x - 2y + 3 = 8 \] To write it in the standard form \( ax + by = c \), we can rearrange it: \[ 4x - 2y = 8 - 3 \] \[ 4x - 2y = 5 \] ### Step 2: Write the second equation in standard form. The second equation is: \[ 3x + 6y = 8y - x + 5 \] First, we rearrange it to bring all terms involving \( x \) and \( y \) to one side: \[ 3x + 6y - 8y + x = 5 \] Combine like terms: \[ 4x - 2y = 5 \] ### Step 3: Compare the two equations. Now we have both equations in standard form: 1. \( 4x - 2y = 5 \) (from the first equation) 2. \( 4x - 2y = 5 \) (from the second equation) ### Step 4: Determine the number of solutions. Since both equations are identical, they represent the same line on a graph. Therefore, the system of equations has infinitely many solutions. ### Final Answer: The system of equations has infinitely many solutions. ---
