Add the two equations you get 5y = 60 so y = 12 and x = 2
They are parallel.
y = -2x+10
2x+y=1
4x + 2y = 20 2y = -4x + 20 y = -2x + 10.......but you may also write it as y = 10 - 2x.
2x + y = 20 y = -2x + 20 Slope = -2 m=-2
y= -2x
Y = 2x + 1
Add the two equations you get 5y = 60 so y = 12 and x = 2
They are parallel.
y=6x-16 y=-2x+8
Y = 2X + 1 Now it is.
y = -2x+10
How do you add 2x plus 3y equals 18 in 5x-y equals 11
No they are parallel.
2x+y=1
2y + 2x = 20 y - 2x = 4 Add the two equations: 3y = 24 so that y = 8 Substitute this value of y in the second equation: 8 - 2x = 4 then 4 = 2x so that x = 2 Thus the ordered pair (y,x) = (8,2)
