2x squared plus 2x plus xy plus y or 2x(x+1) + y(x+1) or (x+1)(2x+y)
Y = 2x-5 and Y = 2x plus 7 is a linear system which intersects at points (-2,2)
Y = 2x + 1
(x - 1)(2x + y)
It is 5x+y
2x plus y = -3 (subtract 2x from both sides) y = -2x - 3 slope = -2 y-intercept = -3
2x + y = 7y = -2x + 7
Solve for y.2x+y=5*subtract 2x from both sides*2x+y-2x=5-2xy=-2x+5 / y=5-2x
xy plus 2x plus 4y plus 8 or (xy+2x) + (4y+8) or x(y+2) + 4(y+2) or (x+4)(y+2)
2x + y = 20 y = -2x + 20 Slope = -2 m=-2
[ y = -2x + any other number ] is parallel to [ y = -2x + 6 ].
x + y + x = 2x + y
Because 2x+y is addition not multiplication
It is: y = 2x-3
20x2 + 22xy + 6y2 = 20x2 + 10xy + 12xy + 6y2 = 10x(2x + y) + 6y(2x + y) = (2x + y)(10x + 6y) = 2(2x + y)(5x + 3y)
X + ( 2Y - 2X - Y ) is equal to Y - X
It is -2x + Y. For anything more you would need to know the values of x and/or Y.
The value of y in the equation -2x plus 4y -4, is 1 plus x/2.
When using substitution the answer to y0.5x plus 2 -y-2x plus 4 is y = -2 (x-1.
