1.2z is a like term. y and 1.2y is not like terms because there are two of them.
To simplify the expression (2w + 2x - 12y + 7w + 9x + 6y), combine like terms. First, combine the (w) terms: (2w + 7w = 9w). Next, combine the (x) terms: (2x + 9x = 11x). Finally, combine the (y) terms: (-12y + 6y = -6y). The simplified expression is (9w + 11x - 6y).
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
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 you mean, "x-3y = 12", then xy = 3y2 + 12y.
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
To simplify the expression 2x + 3y + 4x + 9y, you first combine like terms. Adding the coefficients of x terms gives 2x + 4x = 6x. Similarly, adding the coefficients of y terms gives 3y + 9y = 12y. Therefore, the simplified expression is 6x + 12y.
12y = 132y = 132/12y = 11
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.
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
