how do this problem 4y+3(2y-4)=y
Start with the multiplication shown by the parentheses
4y + 3(2y - 4) = y
4y + 6y - 12 = y
You need the y term on the right side moved to the left side
4y + 6y - 12 - y = y - y
9y - 12 = 0
Now, deal with the constant term
9y - 12 + 12 = 0 + 12
9y = 12
Last, divide by 9
9y / 9 = 12 / 9
y = 12/9
y = 4/3
