In the problem below, which line contains an error? Circle your answer Line 1: − 5(x − 3) − 2x = 46 − 4(x + 1) Line 2: − 5x + 15 − 2x = 46 − 4x − 4 Line 3: − 3x + 15 = − 4x + 42 Line 4: x + 15 = 42 Line 5: x = 27 In which line you chose why is it wrong?

Line 3 is incorrect

Step-by-step explanation:

Required

Which line is wrong and why
