It is -2x + Y. For anything more you would need to know the values of x and/or Y.

Y = 2x-5 and Y = 2x plus 7 is a linear system which intersects at points (-2,2)
y= -2x
Y = 2x + 1
2x plus y = -3 (subtract 2x from both sides) y = -2x - 3 slope = -2 y-intercept = -3
xy plus 2x plus 4y plus 8 or (xy+2x) + (4y+8) or x(y+2) + 4(y+2) or (x+4)(y+2)
(x - 1)(2x + y)
2x+y=1
Solve for y.2x+y=5*subtract 2x from both sides*2x+y-2x=5-2xy=-2x+5 / y=5-2x
It is 5x+y
2x + y = 7y = -2x + 7
20x2 + 22xy + 6y2 = 20x2 + 10xy + 12xy + 6y2 = 10x(2x + y) + 6y(2x + y) = (2x + y)(10x + 6y) = 2(2x + y)(5x + 3y)
