The correct Answer is:
To solve the system of equations given by: 1. \( 2x - 5y + 4 = 0 \) (Equation 1) 2. \( 2x + y - 8 = 0 \) (Equation 2) we will use the elimination method. ### Step 1: Rearranging the equations First, let's rearrange both equations into the standard form \( Ax + By + C = 0 \). From Equation 1: \[ 2x - 5y + 4 = 0 \implies 2x - 5y = -4 \] From Equation 2: \[ 2x + y - 8 = 0 \implies 2x + y = 8 \] ### Step 2: Subtract Equation 2 from Equation 1 Now, we will subtract Equation 2 from Equation 1 to eliminate \(2x\): \[ (2x - 5y) - (2x + y) = -4 - 8 \] This simplifies to: \[ -5y - y = -12 \] \[ -6y = -12 \] ### Step 3: Solve for \(y\) Now, divide both sides by -6: \[ y = \frac{-12}{-6} = 2 \] ### Step 4: Substitute \(y\) back into one of the original equations Now that we have \(y = 2\), we can substitute this value back into Equation 2 to find \(x\): \[ 2x + 2 - 8 = 0 \] This simplifies to: \[ 2x - 6 = 0 \] \[ 2x = 6 \] ### Step 5: Solve for \(x\) Now, divide both sides by 2: \[ x = \frac{6}{2} = 3 \] ### Final Solution The solution to the system of equations is: \[ x = 3, \quad y = 2 \]
