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 the equation Factorise x3 4x?
X(X2 - X)
What is x3 equal 4x?
It is a cubic equation in the variable x.
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.
What is the solution to the equation below 4x equals x plus 15?
If: 4x = x+15 Then: x = 5
Solve 4x equals 16?

What is the answer to this equation -20 equals -4x-6x?
-20 = -4x - 6x-20 = -10x20 = 10x2 = x
Solve for x in the following equation 4X - 7 equals 2?
4x-7=24x=9 x=9/4
2x plus y equals 3 2y-6 equals -4x?
4x + 2y = 6 (first equation x 2) 4x + 2y = 6 (second equation rearranged) No unique answer exists
What is 4x-1 equals 9 is it an expression?
4X - 1 = 9 Is an equation. 4X - 1 = 9 4X = 10 X = 5/2 =====
