It is a linear expression. Since it is neither an equation, nor an inequality, it cannot be solved. Also, since the values of x and y are unknown, it cannot be evaluated.
4xy - 2y(x + 4) = 4xy - 2xy - 8y = 2xy - 8y = 2y(x - 4)
The answer to x2 - 2x - 4y2 - 4y =(x - 2y)(x - 2y - 2)
Collect like terms: 3x - x + 4x - 4y + 6y + 2 = 6x + 2y + 2
2xy - 4x plus 8y - 16 equals x plus 4 in parentheses multiplied by 2y minus 4 in parentheses. So, the factors are ( x + 4) and ( 2y - 4) .
2y(x+2)=
-2y=x+8 is the answer
(2y - 5)(y - 2)
Without an equality sign and not knowing the plus or minus values of 2y and 5 it can't be considered to be a straight line equation.
2+2y+x+xy=(x+2)(y+1)
Exactly (2y + 4) .
x=2y-1
8y-7x
