4. For which value of a will the equation 3x – 2 = 3x – a have an infinite number of solutions? Option 1: 2 Option 2: 3 Option 3: 4 Option 4: 5 5. Jenny solved the equation 1 – (2x + 4) = -4x + 5. Her work is shown below. Identify and explain Jenny's error in solving the equation. Line 1: 1 - ( 2x + 4 ) = -4x +5 Line 2: 1 - 2x + 4 = -4x +5 Line 3: 5 - 2x = -4x + 5 Line 4: 2x = 0 Line 5: x = 0 6. Re-solve the equation 1 – (2x + 4) = -4x + 5 to find the correct solution.
