In **algebra**, it is easy to **find** the third **value** when two **values** are given. Generally, the **algebraic** expression should be any one of the forms such as addition, subtraction, multiplication and division. To **find the value of x**, bring the variable to the left side and bring all the remaining **values** to the right side.

Along with it, how do you find the value of x in an equation with brackets?

Into the bargain, how do you find the value of x in a fraction equation? How to Solve for **x** in **Fractions**. Solve for **x** by cross multiplying and simplifying the **equation** to **find x**. Example: Given the **equation** 4/10 = **x**/15 solve for **x**. Since 60 = 60 is true, you can be sure that **x** = 6 is the correct answer.

One way or another, what are the 4 steps to solving an equation?

We have **4** ways of **solving** one-**step equations**: Adding, Substracting, multiplication and division. If we add the same number to both sides of an **equation**, both sides will remain equal. If we subtract the same number from both sides of an **equation**, both sides will remain equal.

How do you find the value of algebra?

To evaluate an **algebraic** expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we **know the value** of our variables, we can replace the variables with their **values** and then evaluate the expression.

Isolate **x** by dividing each term by the **x** coefficient. Just divide 3x and 9 by 3, the **x** term coefficient, to **solve for x**.

The letter "**x**" is often used in algebra to mean a **value** that is not yet known. It is called a "variable" or sometimes an "unknown". In **x** + 2 = 7, **x** is a variable, but we can work out its **value** if we try! A variable doesn't have to be "**x**", it could be "y", "w" or any letter, name or symbol. See: Variable.

Do unto one side of the **equation**, what you do to the other! When **solving** math **equations**, we must always keep the 'scale' (or **equation**) balanced so that both sides are ALWAYS equal.

In a **two**-**variable** problem rewrite the **equations** so that when the **equations** are added, one of the **variables** is eliminated, and then **solve** for the remaining **variable**. Step 1: Multiply **equation** (1) by -5 and add it to **equation** (**2**) to form **equation** (3) with just one **variable**.

If the **equation** is in the form, ax + b = c, where x is the **variable**, you can solve the **equation** as before. First βundoβ the addition and subtraction, and then βundoβ the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the **equation** to get the term with the **variable** by itself.

In the 2012 TED Talk above, Terry Moore traces the use of the letter **x** in algebra to the Arabic word al-shalan, which means "the unknown thing," claiming that, in translations of the writing of Arabic mathematicians, that word became linked to the Greek letter chi and then reached us through Latin and, eventually, ...
