Solve three or more step linear equations, with the variable on one side, with all positive integers Tom and Katie are discussing how to solve:
\(
 \frac{3 x}{2} + 1 =5 
\)

Tom says a correct next line of working could be: \( \frac{3 x}{2}=4 \)

Katie says a correct next line of working could be: \( 3 x+1=10 \)

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
