35x2 - 38x + 8
If you mean 38x = 133 then the value of x works out as 3.5
-6 + 4x + (9-2x) = -6 + 4x + 9 - 2x = [ 3 + 2x ]
2x + 1 = 9 2x = 9 - 1 2x = 8 2x/2 = 8/2 x=4
4-2x-9 = -19 -2x = -19-4+9 -2x = -14 x = 7
x-8=2x*19 x-8=38x x=38x+8 (-37)x=8 x=-8/37≈-0.2162162162162
35x2 - 38x + 8
It is an algebraic expression involving x. Of do you mean 'what is x if 2x - 9 equals 9?' 2x - 9 = 9 ⇒ 2x - 9 + 9 = 9 + 9 ⇒ 2x = 18 ⇒ 2x ÷ 2 = 18 ÷ 2 ⇒ x = 9
4x2 - 36x + 81 = 4x2 - 18x - 18x +81 = 2x(2x - 9) - 9(2x - 9) = (2x - 9)2
If 9-2x =35 -2x = 35-9 -2x = 26 -x = 13 x = -13
If you mean 38x = 133 then the value of x works out as 3.5
If: 9-2x = 35 Then: -2x = 35-9 => -2x = 26 So: x = -13
-6 + 4x + (9-2x) = -6 + 4x + 9 - 2x = [ 3 + 2x ]
2x-1=9 2x=10 x=5
2x + 1 = 9 2x = 9 - 1 2x = 8 2x/2 = 8/2 x=4
2x+1 = 9 2x = 9-1 2x = 8 x = 4
4-2x-9 = -19 -2x = -19-4+9 -2x = -14 x = 7
