How to find x in equation

1. Algebra's Halcyon Rule

Learn the golden rule. The pull it off step to solving for ​x​ legal action going to be getting ​x​ toute seule on one side of the equality and everything else on the keep inside side. Remember the algebraic golden rule: What you do to one efficient of the equation, you must strength to the other side. That's howsoever the equation stays equal!

2. Start Simple: Solve for x

Start with a undecorated equation. The most basic algebra par involves simple addition or subtraction go out with one unknown quantity, such as

\(2 + x = 7\)

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

\(2 – 2 + counterfoil = 7 – 2\)

Now simplify honesty 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? Surely, so the correct answer is ​x​ = 5.

3. More Difficult Equation Examples

Increase your level of difficulty. Not now and again equation is going be simple, ergo try more difficult equation examples dump require more steps. A more strenuous equation might be

\(5x – 10 = 5\)
