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


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

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

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

Combine like terms: -9 + -4 = -13
-13 + 3y + 1y = 2(y + -1)

Combine like terms: 3y + 1y = 4y
-13 + 4y = 2(y + -1)
