Simplify algebraic expressions to maintain equivalence by collecting like terms involving just two linear variables Jo and Paul are talking about which term could replace the star in this addition pyramid.
Jo says it could be: \( f \)
Paul says it could be: \( g \)
Who is correct? ![A diagram showing 3 rows of boxes. the bottom row has 3 boxes, containing a star, and empty box and 2g from left to right. The next row up contains two boxes, overlapping the joins of the boxes below. The left one contains 4f+6g, the right one is empty. The top row is one box, centered over the join of the two below, it is empty.]() Only

Assumes an addition pyramid works in a different way to how it actually does
