Solution for (4-y)(3y-7)=0 equation:


Simplifying
(4 + -1y)(3y + -7) = 0

Reorder the terms:
(4 + -1y)(-7 + 3y) = 0

Multiply (4 + -1y) * (-7 + 3y)
(4(-7 + 3y) + -1y * (-7 + 3y)) = 0
((-7 * 4 + 3y * 4) + -1y * (-7 + 3y)) = 0
((-28 + 12y) + -1y * (-7 + 3y)) = 0
(-28 + 12y + (-7 * -1y + 3y * -1y)) = 0
(-28 + 12y + (7y + -3y2)) = 0

Combine like terms: 12y + 7y = 19y
(-28 + 19y + -3y2) = 0
