(4y+3)(6+y)=0

Solution for (4y+3)(6+y)=0 equation:

Simplifying
(4y + 3)(6 + y) = 0

Reorder the terms:
(3 + 4y)(6 + y) = 0

Multiply (3 + 4y) * (6 + y)
(3(6 + y) + 4y * (6 + y)) = 0
((6 * 3 + y * 3) + 4y * (6 + y)) = 0
((18 + 3y) + 4y * (6 + y)) = 0
(18 + 3y + (6 * 4y + y * 4y)) = 0
(18 + 3y + (24y + 4y2)) = 0

Combine like terms: 3y + 24y = 27y
(18 + 27y + 4y2) = 0

Solving
18 + 27y + 4y2 = 0

Solving for variable 'y'.
