Linear equations dot to dot

Solve these increasingly difficult linear equations (although they are all one sided) and join question number to answer. e.g. Q1 has answer 37 so join 1 to 37. Next do Q37. Encourage students to do it this way so they gradually build up to the harder questions.Have rough paper or mini whiteboards on hand for trickier ones which may require flow charts or balancing. The answer to the joke is 'Nice Belt'.
