Find the value of x class 7

1. Algebra's Golden Rule

Learn the golden rule.

Solve for x problems and answers

The first step to solving for ​x​ is going to be getting ​x​ alone on one side of the equation and everything else on the other side. Remember the algebraic golden rule: What you do to one side of the equation, you must do to the other side.

That's how the equation stays equal!

2. Start Simple: Solve for x

Start with a simple equation.

How to find x formula

The most basic algebra equation involves simple addition or subtraction with one unknown quantity, such as

\(2 + x = 7\)

How do you get ​x​ by itself? Subtract 2 from both sides:

\(2 – 2 + x = 7 – 2\)

Now simplify the equation by doing the math:

\(2-2+x=7-2\)
\(0+x=5\)
\(\text{or } x = 5\)

Check your work by substituting the answer, 5, into the equation for ​x​.

Does 2 + 5 = 7? Yes, so the correct answer is ​x​ = 5.

Increase your level of difficulty. Not every equation is going be simple, so try more difficult equation examples that require more steps. A more difficult equation might be

\(5x – 10 = 5\)
