Here are his last two steps:3z+1=3z−11=−1Which statement is true about the equation?(A) The solution is z=−1.(B) There is no solution because 1=−1 is a false equation.(C) There are infinitely many solutions because 1=−1 is a false equation.(D) The solution is (1,−1).
Q. Matt solved the equation 3(z+1)−2=4z−z−1. Here are his last two steps:3z+1=3z−11=−1Which statement is true about the equation?(A) The solution is z=−1.(B) There is no solution because 1=−1 is a false equation.(C) There are infinitely many solutions because 1=−1 is a false equation.(D) The solution is (1,−1).
Simplify left side: Simplify the left side of the equation: 3(z+1)−2=3z+3−2=3z+1
Simplify right side: Simplify the right side of the equation: 4z−z−1=3z−1
Set equal: Set the simplified left side equal to the simplified right side: 3z+1=3z−1
Subtract to isolate: Subtract 3z from both sides to isolate the constants:1=−1
Analyze solution: Analyze the equation 1=−1: Since 1 cannot equal −1, this indicates a contradiction, meaning there is no solution to the equation.
