Solution for 4(y-2)-2(y-1)=3y-(9+y) equation:


Simplifying
4(y + -2) + -2(y + -1) = 3y + -1(9 + y)

Reorder the terms:
4(-2 + y) + -2(y + -1) = 3y + -1(9 + y)
(-2 * 4 + y * 4) + -2(y + -1) = 3y + -1(9 + y)
(-8 + 4y) + -2(y + -1) = 3y + -1(9 + y)

Reorder the terms:
-8 + 4y + -2(-1 + y) = 3y + -1(9 + y)
-8 + 4y + (-1 * -2 + y * -2) = 3y + -1(9 + y)
-8 + 4y + (2 + -2y) = 3y + -1(9 + y)

Reorder the terms:
-8 + 2 + 4y + -2y = 3y + -1(9 + y)

Combine like terms: -8 + 2 = -6
-6 + 4y + -2y = 3y + -1(9 + y)

Combine like terms: 4y + -2y = 2y
-6 + 2y = 3y + -1(9 + y)
-6 + 2y = 3y + (9 * -1 + y * -1)
-6 + 2y = 3y + (-9 + -1y)

Reorder the terms:
-6 + 2y = -9 + 3y + -1y

Combine like terms: 3y + -1y = 2y
-6 + 2y = -9 + 2y

Add '-2y' to each side of the equation.
-6 + 2y + -2y = -9 + 2y + -2y

Combine like terms: 2y + -2y = 0
-6 + 0 = -9 + 2y + -2y
-6 = -9 + 2y + -2y

Combine like terms: 2y + -2y = 0
-6 = -9 + 0
-6 = -9

Solving
-6 = -9
