Understanding One-Step Equations
One-step equations are the simplest form of algebraic equations, involving only one operation. They can be in the form of addition, subtraction, multiplication, or division.
Examples of One-Step Equations
-
Addition Equation:
( x + 3 = 10 )
To solve, subtract 3 from both sides:
( x = 10 - 3 )
So, ( x = 7 ). -
Subtraction Equation:
( y - 5 = 12 )
To solve, add 5 to both sides:
( y = 12 + 5 )
Thus, ( y = 17 ). -
Multiplication Equation:
( 4z = 20 )
To solve, divide both sides by 4:
( z = 20 \div 4 )
Therefore, ( z = 5 ). -
Division Equation:
( \frac{w}{3} = 7 )
To solve, multiply both sides by 3:
( w = 7 \times 3 )
Hence, ( w = 21 ).
Tips for Solving One-Step Equations
- Isolate the variable: Always perform the inverse operation to get the variable alone on one side of the equation.
- Perform the same operation on both sides: This keeps the equation balanced, which is crucial for finding the correct answer.
- Check your work: Substitute your answer back into the original equation to verify it's correct.
Moving to Two-Step Equations
Two-step equations involve two operations and are slightly more complex. They often require isolating the variable by performing two inverse operations.
Examples of Two-Step Equations
-
Addition and Multiplication:
( 2x + 3 = 11 )
First, subtract 3 from both sides:
( 2x = 11 - 3 )
Then, divide by 2:
( x = \frac{8}{2} )
Thus, ( x = 4 ). -
Subtraction and Division:
( 3y - 4 = 11 )
Start by adding 4 to both sides:
( 3y = 11 + 4 )
Then, divide by 3:
( y = \frac{15}{3} )
Therefore, ( y = 5 ).
Tips for Solving Two-Step Equations
- Identify the order of operations: Always start with the operation furthest from the variable and work your way in.
- Keep the balance: Just like in one-step equations, maintain equality by performing the same operations on both sides.
- Double-check your steps: Ensure each step logically follows from the last.
