Solution for y(y+7)+3y=y(y+3)-14 equation:


Simplifying
y(y + 7) + 3y = y(y + 3) + -14

Reorder the terms:
y(7 + y) + 3y = y(y + 3) + -14
(7 * y + y * y) + 3y = y(y + 3) + -14
(7y + y2) + 3y = y(y + 3) + -14

Reorder the terms:
7y + 3y + y2 = y(y + 3) + -14

Combine like terms: 7y + 3y = 10y
10y + y2 = y(y + 3) + -14

Reorder the terms:
10y + y2 = y(3 + y) + -14
10y + y2 = (3 * y + y * y) + -14
10y + y2 = (3y + y2) + -14

Reorder the terms:
10y + y2 = -14 + 3y + y2

Add '-1y2' to each side of the equation.
10y + y2 + -1y2 = -14 + 3y + y2 + -1y2

Combine like terms: y2 + -1y2 = 0
10y + 0 = -14 + 3y + y2 + -1y2
10y = -14 + 3y + y2 + -1y2

Combine like terms: y2 + -1y2 = 0
10y = -14 + 3y + 0
10y = -14 + 3y

Solving
10y = -14 + 3y
