Solve three or more step linear equations, with the variable on one side, involving negative decimals Tom and Katie are discussing how to solve:
\(\frac{5 x}{3}-1=-2.4\)

Tom says a correct next line of working could be: \( 5 x-3=-7.2 \)

Katie says a correct next line of working could be: \( \frac{5 x}{3}=-3.4 \)

Who is correct? Neither is correct

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