(6+y)(5y+1)=0

Solution for (6+y)(5y+1)=0 equation:

Simplifying
(6 + y)(5y + 1) = 0

Reorder the terms:
(6 + y)(1 + 5y) = 0

Multiply (6 + y) * (1 + 5y)
(6(1 + 5y) + y(1 + 5y)) = 0
((1 * 6 + 5y * 6) + y(1 + 5y)) = 0
((6 + 30y) + y(1 + 5y)) = 0
(6 + 30y + (1 * y + 5y * y)) = 0
(6 + 30y + (1y + 5y2)) = 0

Combine like terms: 30y + 1y = 31y
(6 + 31y + 5y2) = 0

Solving
6 + 31y + 5y2 = 0

Solving for variable 'y'.
