If you mean 2x = 28 then the value of x is 14
The idea is to: * Replace "x" by "4" in -2x * Do the calculations * Take the absolute value
28 + 2x = 120 2x = 120 - 28 2x = 92 x = 92/2 x = 46
No. For 0 < x < 2, 2x is larger.
If you mean: 4 = 2x then the value of x = 2
Do you mean "what is the value of x when 3x - 2x = 15?" in that case, the value of x is 15
Formula: % increase=[(new value - old value) / old value] x 100% % increase = (149-124) /124 x 100% = 20.16%
18
If you mean 2x = 28 then the value of x is 14
If you mean: x-3 = 2x-8 then the value of x works out as 5
If you mean the value of 15-2x when x is 2 then it is: 15-4 = 11
The idea is to: * Replace "x" by "4" in -2x * Do the calculations * Take the absolute value
6 + 2x = x - 6 2x - x = -6 -6 x = -12

28 + 2x = 120 2x = 120 - 28 2x = 92 x = 92/2 x = 46
It is 2x + 5. The value of this expression will depend on the value of x: each different value of x will give a different value for the expression.
(2x)2 = 4 x2 Its numerical value depends on the value of 'x'.
