The idea is to:
* Replace "x" by "4" in -2x
* Do the calculations
* Take the absolute value

Solve the absolute value of X plus 1- absolute value of x plus 4 equals 0?
|x + 1| - |x + 4| = 0 ∴ |x + 1| = |x + 4| ∴ x + 1 = -x - 4 ∴ 2x = -5 ∴ x = -5/2
What is 4 2x solved?
If you mean: 4 = 2x then the value of x = 2
Which number is a solution of -2x -4?
If you mean: -2x = -4 then the value of x is 2
What is the value of the x in 2x plus 4 equals 3x?
x = 4
2x plus 36 4?
The value of X in the equation 2x plus 36 = 4 is -16.
Write x2 or x-2 as an inequality containing absolute value?
4
Solve the absolute value of X plus 1- absolute value of x plus 4 equals 0?
|x + 1| - |x + 4| = 0 ∴ |x + 1| = |x + 4| ∴ x + 1 = -x - 4 ∴ 2x = -5 ∴ x = -5/2
Express without absolute value symbols f of x equals absolute value x plus absolute value x-2?
In order to write f(x) = |x| + |x-2| without the absolute value signs, it it necessary to write it as a piecewise function.We must define f as follows:f(x) = -2x + 2, if x < 0f(x) = 2, if 0
What is the absolute value of -19?
The absolute value of 19 is 19. If x is positive , absolute x equals x.
What is 4 2x solved?
If you mean: 4 = 2x then the value of x = 2
If 2x - 6 equals 4 then what is the value of x?
2x -6 = 4 then 2x = 4 +6 x=10/2 = 5
2x - 6 equals 4 then what is the value of x?
2x - 6 = 4 2x = 4 + 6 = 10 x = 10/2 = 5 ∴ x = 5
Which number is a solution of -2x -4?
If you mean: -2x = -4 then the value of x is 2
What is the value of 15-2x 2 when X's?
If you mean the value of 15-2x when x is 2 then it is: 15-4 = 11
If 2x - 6 4 then what is the value of x?
x=5
What is the value of the x in 2x plus 4 equals 3x?
x = 4
Determine all real numbers x such that absolute value of 2x minus 7 greater than 1?
all real numbers such that x is not between 3 and 4
