12y + 5 = 53 12y = 48 y = 4
y^2 - 12y + 36 = 9 subtract 9 from each side y^2 - 12y + 27 = 0 easy factoring by inspection (y - 3)(y - 9) y = 3 y = 9
12y = 8x + 24 so y = 2x/3 + 2
12y+2=146 12y=146-2 12y=144 144/12 12x12=144 y=12
The equation is 12y - 9 = 21. To solve for y, you can start by adding 9 to both sides to isolate the term with y. This gives you 12y = 30. Next, divide both sides by 12 to solve for y, which gives y = 2.5.
12y + 5 = 53 12y = 48 y = 4
If you mean 2y(2xy)(21)=7yx, then... 12y^2 -y=0 y(12y-1)=0 either y=0 or 12y-1=0, so y=1/12
y^2 - 12y + 36 = 9 subtract 9 from each side y^2 - 12y + 27 = 0 easy factoring by inspection (y - 3)(y - 9) y = 3 y = 9
If x - 3y = 12, we can solve for x in terms of y: x = 12 + 3y. Then, to find xy, we multiply x by y: xy = y(12+3y) = 12y + 3y^2.
12y = 8x + 24 so y = 2x/3 + 2
y2 + 12y + 5y + 60 y (y + 12) + 5 (y + 12) (y + 12 )(y + 5)
12y+2=146 12y=146-2 12y=144 144/12 12x12=144 y=12
The equation is 12y - 9 = 21. To solve for y, you can start by adding 9 to both sides to isolate the term with y. This gives you 12y = 30. Next, divide both sides by 12 to solve for y, which gives y = 2.5.
12y = 132y = 132/12y = 11
I assume the expression is y2+12y+27 as I cannot see the operation symbols between them (editor problem?). If you agree with this then y2 + 12y + 27 = y2 + 9y + 3y + 27 = y(y + 9) + 3(y + 9) = (y + 3)(y + 9)
y = 11
