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


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

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

Combine like terms: 4 + 3 = 7
7 + -1y = 3(y + 1) + -4(1 + -1y)

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

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

Combine like terms: 3 + -4 = -1
7 + -1y = -1 + 3y + 4y

Combine like terms: 3y + 4y = 7y
