A number, multiplied by a variable is part of an Algebraic equation. A person can find out the value of the variable if they divide each side by the number that is next to the variable. For example, if the equation is 5x = 60, divide each side by 5 and the answer is x = 12.
When you solve a one-variable equation, your goal is to isolate the variable.To isolate the variable means to make it be alone on one side of the equals sign.In the equation shown here, you can isolate the variable by subtracting 9 from both sides of the equation and simplifying
Math should grow up and learn to solve it's own problems ^^Hope This Helps!
For example, let's start off with: 9x + 3 > 3x + 2First, get rid of the smallest 6x + 3 > 2variable, 3x, by subtracting3x from 9x.Then, subtract 3 from both 6x > -1sides to isolate thevariable.Now divide each side by x > -1/66 to get x alone to solvethe inequality.Summary: Subtract one coefficient from another coefficient to get one coefficient on one side of the equation. Subtract one constant on one side of the equation from the other so that the coefficient is completely alone on its side of the equation. Finally, if their is a constant attached to the variable, which the pair is called a coefficient, divide whatever the constant of the variable is on both sides of the equation to get the variable alone to solve the equation.
Isolating a single variable in terms of the rest of the equation provides a solution to that variable. That is, if you know the equation that equals the variable, then you can figure out its value.
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
3n=36 Write the equation n=12 Divide each side of the equation by 3 to get the variable alone.
Algebraically manipulate the equation until you have the indicated variable on one side of the equation and all of the other factors on the other side.
-- You select an operation. -- You apply the same operation to each side of the equation. -- You keep doing both steps until the equation says (the variable) = (the value of the variable)

Algebra ygb-iboe-hvz is a type of algebraic equation known as a "ygb-iboe-hvz equation". This type of equation is a type of linear equation that is commonly used to solve for the unknown variable in a given equation. The equation is composed of three terms: ygb, iboe, and hvz. The ygb term is the coefficient of the unknown variable, the iboe term is the constant, and the hvz term is the right-hand side of the equation. To solve the equation, the coefficients of each term must be determined and the equation must be rearranged to solve for the unknown variable.

A number, multiplied by a variable is part of an Algebraic equation. A person can find out the value of the variable if they divide each side by the number that is next to the variable. For example, if the equation is 5x = 60, divide each side by 5 and the answer is x = 12.
Divide each side of the equation by 10 .
1. Elimination: Select two equations and a variable to eliminate. Multiply each equation by the coefficient if that variable in the other equation. If the signs of the coefficient for that variable in the resulting equations are the same then subtract one new equation from the other. If they have opposite signs then add them. You will now have an equation without that variable. Repeat will other pairs and you will end up with one fewer equation and one fewer variable. Repeat this process: after each round you will have one fewer equation and one fewer variable. Keep going until you are left with one equation in one variable. Solve that. Then work backwards solving for the other variables.2. Substitution: Select a equation and a variable. Make that variable the subject of the equation. The right hand side of this equation is an expression for that variable. Substitute this expression for the variable is each of the other equations. Again, one fewer equation in one fewer variable. Continue until you are left with one equation in one variable. Solve that. Then work backwards solving for the other variables.3. Matrix inversion: If A is the nxn matrix of coefficients, X is the nx1 [column] matrix of variables and B is the nx1 matrix of the equation constants, then X = A^-1*B where A^-1 is the inverse of matrix A.

(p) is the variable...it can stand for anything, but what you are trying to do is solve for it. 6p+5=29 is simply 4. 1) Get the variable on one side - Subtract 5 from each side: 6p=24 2) If applicable, make it so there is only "one" variable - Divide each side by 6: p=4
