Solve two-step linear equations, with the variable on one side, with all positive integers Tom and Katie are arguing about a first step to solve this equation:
\(
\frac{m}{4}-1=20
\)
Tom says you can write: \( \frac{m}{4}=21 \)
Katie says you can write: \( m-1=80 \)
Who is correct? Only Katie

Does not understand that when multiplying both sides of an equation by an amount every term must be multiplied by the same amount
