∙ 14y ago4x = x - 3 First, subtract x from both sides.
4x - x = x -3 - x
Simplify the equation.
3x = -3
Finally, divide both sides by 3.
x = -3/3 = -1
The answer is negative one (-1).

What is the solution to the equation below 4x equals x plus 15?
If: 4x = x+15 Then: x = 5
If 4x plus 5 equals 2 then what is x?
The equation 4x + 5 = 2 has the solution 4x = -3 and x = - 3/4 (minus 3/4).
What is the number and type of roots of the equation x2-4x-32 equals 0?
There are 2 roots to the equation x2-4x-32 equals 0; factored it is (x-8)(x+4); therefore the roots are 8 & -4.
X3 plus 6x2 - 4x - 24 factor completely?
x3 + 6x2 - 4x - 24 = (x + 6)(x2 - 4) = (x + 6)(x + 2)(x - 2)
How do you determine an equation for the inverse of a function Example f of x equals 9x or g of x equals 4x plus 6?
The inverse of an equation is rewriting it as a function of the other variable. Simply solve the equation for x instead of y. y=9x can be written as x= (1/9)y --> fy=y/9◄ y=4x+6 (or 4x+6=y) -> 4x=y-6 -> x=(y-6)/4 --> gy=(y-6)/4■

How do you solve x³-4x equals 0 algebraically?
Suppose x3-4x = 0. To solve, factor: x3-4x = x(x2-4) = x(x+2)(x-2) = 0 Now, a product equals 0 if and only one or more of the factors equals 0, so set each factor to 0 and solve. The roots are 0,-2 and +2.
Solve 4x equals 16?
4x = 16Divide each side of the equation by 4:x = 4
