Solve two-step linear equations, with the variable on one side, with all positive integers Tom and Katie are discussing how to solve:
\(
\frac{x}{3}-5=12
\)

Tom says a correct next line of working could be: \( \frac{x}{3}=17 \)

Katie says a correct next line of working could be: \( x-5=36 \)
Who is correct? Both Tom and Katie
