2. Solve the equation for x. x = (4 * 15) / 10.
3. Simplify for x. x = 6.

What is the value of the 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!

How do you solve x and y problems?

Solving for two variables (normally denoted as “x” and “y”) requires two sets of equations. Assuming you have two equations, the best way for solving for both variables is to use the substitution method, which involves solving for one variable as far as possible, then plugging it back in to the other equation.

How do you solve for x in a quadratic equation?

Solving Quadratic Equations

1. Put all terms on one side of the equal sign, leaving zero on the other side.
2. Factor.
3. Set each factor equal to zero.
4. Solve each of these equations.
5. Check by inserting your answer in the original equation.

Why do we reduce fractions?

We simplify fractions because it is always to work or calculate when the fractions are in the simplest form.

How do you change a fraction into a mixed number?

To change an improper fraction to a mixed number, follow these steps:

1. Divide the numerator by the denominator.
2. Write down the whole number part of the quotient.
3. Take the remainder and write it over the original denominator.

How to find x in a fraction?

Write down the problem.

Cross multiply. To cross multiply,simply multiply the denominator of each fraction by the numerator of the other fraction.

Combine like terms. Combine the constant terms in the equation to subtract 9 from both sides of the equation.

Isolate x by dividing each term by the x coefficient.

How do you solve equations with fractions?

Solve Equations with Fractions Using the Multiplication Property of Equality. Consider the equation We want to know what number divided by gives So to “undo” the division, we will need to multiply by The Multiplication Property of Equality will allow us to do this. This property says that if we start with two equal quantities and multiply both by the same number, the results are equal.
