2x+3=23 minus 3 from both sides 2x=23-3 so we get 2x=20 divide both sides by 2 to get the value of x x=10
6 + 2x = x - 6 2x - x = -6 -6 x = -12

That doesnt make sense 2x + 8 = 20 Then x = 6
2x -6 = 4 then 2x = 4 +6 x=10/2 = 5
If: 3x+20 = 2x-10 Then: x = -30
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'
That depends what the value of x is.
If the question is in the context of angles, then x + 20 + x + 10 = 90 ie 2x + 30 = 90 or 2x = 60 which gives x = 30
2x+3=23 minus 3 from both sides 2x=23-3 so we get 2x=20 divide both sides by 2 to get the value of x x=10
x+4+2x = x+20 x+2x-x = 20-4 3x = 16 x = 5 and 1/3
2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4
-2x+20 = 3x 20 = 3x+2x 20 = 5x 4 = x So x = 4
Do you mean "what is the value of x when 3x - 2x = 15?" in that case, the value of x is 15
2x-4 = 20 2x = 20+4 2x = 24 x = 12
2x - (8 x 6) = 20 2x = 20 + 48 2x = 68 x = 68/2 x = 34
