eqn 1 Y = 2X + 6
eqn 2 2X - Y = 2
Rearrange eqn2 to isolate Y
eqn2 Y = 2X - 2
so 2X + 6 = 2X - 2
subtracting 2X from both sides we get
6 = -2
As this is impossible this set of equations can not be solved.

4x2 plus 2xy-3y2 plus -2x2 plus 5xy-2y2?
4x^2+2xy-3y^2-2x^2+5xy-2y2Collect the like terms=2x^2+7xy-5y^2We cannot factorise it because the end term is a negative whilst the second-last term is positive.
What is the factor for 4x squared - 4x plus 2xy -2y?
2(x - 1)(2x + y)
Factor 2xy plus 4x plus 8y plus 16?
2xy + 4x + 8y + 16 = 2[xy + 2x + 4y + 8] = 2[x(y + 2) + 4(y + 2)] = 2(y + 2)(x + 4)
Evaluate 2xy when x equals 30 and y equals 2?
2xy=2*30*2=120
What is the answer to x - 2 2x plus 1 or 10 -2x plus 2 equals?
2 plus 1-x divided by.
Factor 2xy - 4x plus 8y - 16?
( 2xy - 4x ) + ( 8y - 16)2 ( xy - 2x ) + 2 ( 4y - 8 ) Answer
2xy - 4x plus 8y - 16?
2xy - 4x + 8y - 16 can be factored.(2xy - 4x) + (8y - 16)2x(y - 2) + 8(y - 2)Since y-2 is the same as the other, it would turn out like this:(2x + 8)(y - 2):]
What does 2x plus 2y equals?
(2x + 2y) is exactly the same thing as 2(x+y). In order to know how much it actually is, you have to know the numerical values of both 'x' and 'y'.
Factor 4x squared plus 4x plus 2xy plus 2y?
2 (2x2 + 2x + xy + y ) it's 2 (2x + y)(x + 1) if you're doing A+
