Add the two equations you get 5y = 60 so y = 12 and x = 2
4x+2y = 20 2y = -4x+20 y = -2x+10
4x + 2y = 20 2y = -4x + 20 y = -2x + 10.......but you may also write it as y = 10 - 2x.
y = -2x+10
y=16 x= -4
The result of the equation x + 2y - 2x - y equals x simplifies to y - x.
4x+2y = 20 2y = -4x+20 y = -2x+10
4x + 2y = 20 2y = -4x + 20 y = -2x + 10.......but you may also write it as y = 10 - 2x.
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
y = -2x+10
-2x=2y+5 +2x -2y -2y=2x+5 /-2 y=-1/1+2.5
The solution is:- x = 0 and y = 5
y=16 x= -4
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
