20x=130 x=130/20 x=6.5 or 13/2
2x + 20x = 111,45222x = 111,452x = 5,066
x = -1.75
140/20=7
Improved Answer:-If: 20x+27 = 143Then: x = 5.8
50x squared equals 20x-2 equals zero is not possible, for 20x-2 = 0 --> x = 1/10 While 50x2 = 0 means that x should be zero. So either 50x2 =/ 20x-2 or 20x-2 =/ 0
20x=130 x=130/20 x=6.5 or 13/2
The graphs of the two equations will intersect when x² + 20x + 100 = y = x² - 20x + 100 Subtracting x² +100 from both sides you get 20x = -20x that will only be true when x = 0. At x = 0, y = 100 for both equations - so the point of contact would be (0,100)
x+20x = 60000 21x = 60000 x = 60000/21 = 2857.'142857' recurring

If: y = x2+20x+100 and x2-20x+100 Then: x2+20x+100 = x2-20x+100 So: 40x = 0 => x = 0 When x = 0 then y = 100 Therefore point of intersection: (0, 100)
20x + 5 - 20 = 21x + 4 -x = 4 + 15 x = -19
20 + x = 55x = 55 -20x= 35
