To expand the expression (3y + 1)(x + 2y - 4), we can use the distributive property and multiply each term of the first expression by each term of the second expression:

(3y + 1)(x + 2y - 4) = 3y * (x + 2y - 4) + 1 * (x + 2y - 4)

Expanding further:

= 3xy + 6y² - 12y + x + 2y - 4

Combining like terms:

= 3xy + 6y² + x + (-12y + 2y) - 4

= 3xy +
