If: 20x = 3.65 Then: x = 0.1825
20x=130 x=130/20 x=6.5 or 13/2
2x + 20x = 111,45222x = 111,452x = 5,066
x = -1.75
Improved Answer:-If: 20x+27 = 143Then: x = 5.8
it depends on what x is if it was 7 then yes it would equal 140
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
x+20x = 60000 21x = 60000 x = 60000/21 = 2857.'142857' recurring
... You have to know what x and y are first.
4x =20x=20/4x=5
x2 + 20x - 39 = 0: Add 61 giving: x2 + 20x + 100 = (x + 10)2
If the equation is -20x-5y=40 then the answer is -5y=20x+40 which equals y=-4x-8 If the equation is -20x+5y=40 then the answer is 5y=20x+40 which equals y=4x+8
x2 + 36 = 20x so x2 - 20x + 36 = 0 so x2 - 2x - 18x + 36 = 0 or x(x - 2) - 18(x - 2) = 0 that is (x - 2)(x - 18) = 0 so x - 2 = 0 or x - 18 = 0 ie x = 2 or x = 18
x2 + 20x +0 =30 [(20/2)2 =100] x2 + 20x + 100 =30 +100 √(x+10)2=√130 x+10=√130 x= −10+√130 √ means square root
1 x 140, 2 x 70, 4 x 35, 5 x 28, 7 x 20, 10 x 14 = 140
% rate: = (42/140) x 100% = 0.30 x 100% = 30%
2x + 5 = 25 2x = 20x = 10
