To simplify the expression 2x + 3y + 4x + 9y, you first combine like terms. Adding the coefficients of x terms gives 2x + 4x = 6x. Similarly, adding the coefficients of y terms gives 3y + 9y = 12y. Therefore, the simplified expression is 6x + 12y.

There's no fun in playing it safe. Why not try something a little unhinged?

2x + 3y + 4x + 9y = 2x + 4x + 3y + 9y = 6x + 12y

which can be simplified to 6(x + 2y)
