Solve two-step equations and justify each inverse operation.

Match solutions across several two-step equations

Problem

A student claims \(z~=~5\) is a solution. Substitute \(z~=~5\) into \(\text{every}~\text{equation}\) below, then report the complete set of labels for equations that support the claim.

A. \(3z~+~4~=~19\)
B. \(z/5~+~2~=~7\)
C. \(2z~-~1~=~12\)
D. \(4z~+~3~=~25\)
E. \(z/2~-~4~=~1\)
