What Are Linear Equations? 📏
Linear equations are mathematical statements that show the equality of two expressions that have one or more variables. A typical form of a linear equation in one variable is:
[ ax + b = c ]
Where:
- ( a ) is the coefficient of ( x ),
- ( b ) is a constant,
- ( c ) is another constant.
The goal of solving a linear equation is to isolate the variable on one side of the equation, resulting in a solution that indicates the value of the variable.
Steps to Solve Linear Equations 🛠️
To effectively solve linear equations, follow these steps:
- Simplify Both Sides: If necessary, distribute and combine like terms on both sides of the equation.
- Isolate the Variable: Use inverse operations to get the variable by itself on one side of the equation.
- Check Your Solution: Substitute your solution back into the original equation to verify it’s correct.
Example Problem
Consider the equation:
[ 2x + 3 = 11 ]
Step 1: Subtract 3 from both sides:
[ 2x = 11 - 3 ] [ 2x = 8 ]
Step 2: Divide both sides by 2:
[ x = \frac{8}{2} ] [ x = 4 ]
Step 3: Verify:
Substitute ( x = 4 ) back into the original equation:
[ 2(4) + 3 = 11 ] [ 8 + 3 = 11 ]
Since both sides are equal, the solution ( x = 4 ) is correct! ✅
