It means you keep re-arranging the equation until it ends up in the form "x = "
x is isolated on one side of the equals sign. On the other side of the equals sign will be an expression that might contain other variables but not x.

How do you solve the equation y equals x squared?
If you are solving for y, it is fine. If you are solving for x, divide both sides by x and the equation should be x = y/x
When twelve is subtracted from twice some number the result is 6?
If you are looking for what number it is, it can be described by this equation: 2x-12=6. Solving this equation x=9.
Equation for solving a cubic equation?
Put simply, the equation for solving a cubic equation is x2 + 2ax +b = (x+a)2 + b-a2. This leads to x = -a +/- (a2 -b)1/2.
Why does y equals 0 when solving a quadratic equation?
Because when your solving a quadratic equation your looking for x-intercepts which is where why equals 0 and x equals what ever the answer is.
If 4 more than twice a certain number is 3 less than that number what is the number?
the equation is 2x + 4 = x - 3 solving it yields x = -7
How do you calculate roots?
The roots of an equation in two variables is calculated by setting the dependent variable, y, equal to 0 and then solving the resulting equation for the independent variable, x. The procedure for solving the equation in x will depend on the nature of the equation.
What is the solution to y equals negative x plus 2?
solving for y: y = - x + 2solving for x: x = -y + 2solving for an actual number: you can't. there isn't a way to get a number out of that equation.
What does it mean when the result of solving a linear equation is x equals 0?
Solving a one variable linear equation involves getting the variable on one side of the equals sign by itself. To do this one uses the properties of numbers.
How is solving a two step equation like solving one step equation?
the alikes of solving a one-step or two-step equation: in solving an equation is to have only variables on one side of the equal sign and numbers on the other side of the equal sign. The other alike is to have the number in front of the variable equal to one the variable does not always have to be x. These equations can use any letter as a variable.
What does x mean in the equation 10y equals 5x plus 95x?
Do not write an equation in words!!! What does x mean in 10y = 5x + 95x? It is a place holder for a number. Any number.
Is 0.135135135135 rational?
I assume you mean that it continues indefinitely. ANY number which repeats periodically, ad infinitum, is a rational number. You can convert this one into a fraction (showing that it is a rational number) as follows:Let: x = 0.135135... 1000x = 135.135135... Subtract the first equation from the second one. Solving for "x", you get "x" (your original number) as a fraction.
When 4 times a number is subtracted from 7 times the number the result is 27 What is the number?
Let's call the number x. The given equation can be written as 7x - 4x = 27. Simplifying the equation, we get 3x = 27. Solving for x, we find that x = 9. Therefore, the number is 9.
