Solution for (3y+5)(y+6)=-3(3y+5) equation:


Simplifying
(3y + 5)(y + 6) = -3(3y + 5)

Reorder the terms:
(5 + 3y)(y + 6) = -3(3y + 5)

Reorder the terms:
(5 + 3y)(6 + y) = -3(3y + 5)

Multiply (5 + 3y) * (6 + y)
(5(6 + y) + 3y * (6 + y)) = -3(3y + 5)
((6 * 5 + y * 5) + 3y * (6 + y)) = -3(3y + 5)
((30 + 5y) + 3y * (6 + y)) = -3(3y + 5)
(30 + 5y + (6 * 3y + y * 3y)) = -3(3y + 5)
(30 + 5y + (18y + 3y2)) = -3(3y + 5)

Combine like terms: 5y + 18y = 23y
(30 + 23y + 3y2) = -3(3y + 5)

Reorder the terms:
30 + 23y + 3y2 = -3(5 + 3y)
30 + 23y + 3y2 = (5 * -3 + 3y * -3)
30 + 23y + 3y2 = (-15 + -9y)

Solving
30 + 23y + 3y2 = -15 + -9y

Solving for variable 'y'.

Reorder the terms:
30 + 15 + 23y + 9y + 3y2 = -15 + -9y + 15 + 9y

Combine like terms: 30 + 15 = 45
45 + 23y + 9y + 3y2 = -15 + -9y + 15 + 9y

Combine like terms: 23y + 9y = 32y
45 + 32y + 3y2 = -15 + -9y + 15 + 9y
