3(x-3y)
Factorising 15x-27xy gives 3x (5 - 9y).Factorising is to express a number or expression as a product of factors.When factorising always look for common factors. To factorise (15x-27xy) look for the highest factor between the two terms (3x). 15x - 27y = 3x (5 - 9y)

factor out a 3x 3x(x-3)=3x2-9x
Since 3x is a factor of 3x^2, it is automatically the GCF.
Since 3x is a factor of 12x, it is automatically the GCF.
(3x - 7y)(2x + 9y)
If that's -18y2, the answer is (3x - 2y)(x + 9y)
-3x+9y = 6 9y = 3x+6 y = 1/3x+2/3
3x-9y-27
If you mean: -3x+9y = -6 then it is y = 1/3x-2/3
3x - 9y = 27-9y = -3x + 279y = 3x - 27y = x/3 - 3The graph is a straight line, with (slope = 3), and passing through the point (y = - 3) on the y-axis.
A linear equation in the form y = mx + c has slope m Any line parallel to 3x + 9y = 5 has the same slope 3x + 9y = 5 → 9y = -3x + 5 → y = (-3/9)x + 5/9 → y = -⅓x + 5/9 → Every line parallel to 3x + 9y = 5 has slope -⅓.
3x-2y+9+9y-x = 2x+7y+9
9y-81=9*(y-9)
Factorising 15x-27xy gives 3x (5 - 9y).Factorising is to express a number or expression as a product of factors.When factorising always look for common factors. To factorise (15x-27xy) look for the highest factor between the two terms (3x). 15x - 27y = 3x (5 - 9y)
The expression "75 3X plus 9Y" seems unclear due to the formatting, but if you mean to simplify or evaluate it, it appears to represent the algebraic expression (75 \cdot 3X + 9Y). Simplifying this, you would get (225X + 9Y). If there are specific values for (X) and (Y), you could substitute them in to find a numerical answer.
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
