Y = 2x-5 and Y = 2x plus 7 is a linear system which intersects at points (-2,2)
3y = 2x + 15
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
4
3x + 5 + x + 10 + 2y 4x + 2y + 15 |:2 2x + y + 7.5 2x + y + 7.5 is equivalent to the original.
Y = 2x-5 and Y = 2x plus 7 is a linear system which intersects at points (-2,2)
y= -2x
Y = 2x + 1
-2x + 2y = 4 is equivalent to twice -2 + y = 2 which is the equation of a straight line.
3y = 2x + 15
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
