2x = -x +9
4x+9=2x-6 2x=-15 x=-7.5 x equals -7.5.
2x-9=7 2x=16 X=8
-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4
2x = 18 then x = 18/2 = 9
2x = -x +9
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
If 5 x equals 9 plus 2x then x equals?
4x+9=2x-6 2x=-15 x=-7.5 x equals -7.5.
2x-9=7 2x=16 X=8
-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4
2x = 18 then x = 18/2 = 9
2x+3=9 2x=9-3 2x=6 2x/2=6/2 X=3
If: 9-2x = 35 Then: -2x = 35-9 => -2x = 26 So: x = -13
5x + x - 6x + 2x = 2x
if 2x+3=9 then 2x=6 so x=3
2x-3=9 so 2x=12 and x=6
