There are no exclude values of the equation, as given.
2x + 12 = 2*x + 2*6 = 2*(x + 6)
(2x)2 = 4 x2 Its numerical value depends on the value of 'x'.
18
2x + 4 = 16 2x = 16 - 4 2x = 12 x = 12/2 x = 6
8
If you mean: x-3 = 2x-8 then the value of x works out as 5
According to the given length & width, the diagonal must be 15 cm.So,2X - 11 = 152X = 26X = 13
The answer depends on the sign preceding the value 15 (which is not given in the question). If y = -2x+15 then (0,15) if y= -2x-15 then (0,-15)
Without an equality sign and not knowing the plus or minus values of the given terms it follows that no solution is possible.
6 + 2x = x - 6 2x - x = -6 -6 x = -12
12+2x = 6x-18 12+18 = 6x-2x 30 = 4x Divide both sides of the equation by 4 to find the value of x: x = 7.5
2x - 4 = 12Add 4 to each side:2x = 16Divide each side by 2:x = 8
There are no exclude values of the equation, as given.
7 is wrong, its 8.
