Find the value of 'x' when 2x+8=4x+20
First subtract '2x' from both sides.
8=2x+20
Then subtract '20' from each side.
-12=2x
Then divide each side by '2'
-6=x.
Therefore 'x=-6'
-2x+14=20 x=-3
It is an equation and the value of x is 1
-2x+20 = 3x 20 = 3x+2x 20 = 5x 4 = x So x = 4
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
it equals 13X.
-2x+14=20 x=-3
8
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
It is an equation and the value of x is 1
2x + y = 20 y = -2x + 20 Slope = -2 m=-2
x+4+2x = x+20 x+2x-x = 20-4 3x = 16 x = 5 and 1/3
-2x+20 = 3x 20 = 3x+2x 20 = 5x 4 = x So x = 4
The value of x is 1
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
it equals 13X.
x = 20
2x + 20x = 111,45222x = 111,452x = 5,066
