Simplifying
(7 + -1y)(5y + -3) = 0

Reorder the terms:
(7 + -1y)(-3 + 5y) = 0

Multiply (7 + -1y) * (-3 + 5y)
(7(-3 + 5y) + -1y * (-3 + 5y)) = 0
((-3 * 7 + 5y * 7) + -1y * (-3 + 5y)) = 0
((-21 + 35y) + -1y * (-3 + 5y)) = 0
(-21 + 35y + (-3 * -1y + 5y * -1y)) = 0
(-21 + 35y + (3y + -5y2)) = 0

Combine like terms: 35y + 3y = 38y
(-21 + 38y + -5y2) = 0
