User: (12y3 + 9 y2 + 21y)

Weegy: x+3y=-15 3y=-x-15 y=(-1/3)x-5
user1583|Points 1061|

User: (10x2 – 14x – 12) ÷ (5x + 3)

Weegy: x=2

User: (4x + 1 )(x2 – 9x + 5)

Weegy: Best Answer - Chosen by Voters ((4/x) - (2/4x)) / ((1/2x) + (3/2x)) = ((16/4x) - (2/4x))/(4/2x) = (14/4x)/(2/x) = (14/4x) * (x/2) = 14x/8x = 14/8 = 7/4
