If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines
They are parallel lines.
-6y + 14 + 4y = 32-2y = 32 - 14-2y = 18y = - 9

The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
All that can be deduced is that x + y = 14.
2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7
-2x=2y+5 +2x -2y -2y=2x+5 /-2 y=-1/1+2.5
X + ( 2Y - 2X - Y ) is equal to Y - X
The result of the equation x + 2y - 2x - y equals x simplifies to y - x.
2y = 4x + 4y = 2x + 2
2y = -10y = -58 - 2x - 2(-5) = -108 - 2x + 10 = -10-2x = -10 - 182x = 28x = 14Check:2y = 8 - 2x - 2y = -102(-5) = 8 - 2(14) - 2(-5) = -10-10 = 8 - 28 + 10 = -10-10 = -20 + 10 = -10-10 = -10 = -10
