Solving one-step equations is simple. Following the following steps to solve one-step equations easily.

## Step by step guide to solve one–step equations

- The values of two expressions on both sides of an equation are equal. \(ax \ + \ b=c\)
- You only need to perform one Math operation in order to solve the one-step equations.
- To solve one-step equation, find the inverse (opposite) operation is being performed.
- The inverse operations are:

Addition and subtraction

Multiplication and division

### Example 1:

Solve this equation**.** \(2x=16, x=?\)

**Solultion:**

Here, the operation is multiplication (variable \(x\) is multiplied by \(3\)) and its inverse operation is division. To solve this equation, divide both sides of equation by \(2\):

\(2x=16→2 \ x \ ÷ \ 2=16 \ ÷ \ 2→x=8\)

### Example 2:

Solve this equation**.** \(x \ + \ 12=0, x=?\)

**Solultion:**

Here, the operation is addition and its inverse operation is subtraction. To solve this equation, subtract \(12\) from both sides of the **equation**: \(x \ + \ 12 \ − \ 12=0 \ − \ 12 \)

Then simplify: \(x \ + \ 12 \ − \ 12=0 \ − \ 12 → x= \ − \ 12 \)

### Example 3:

Solve this equation. \( x+24=0 ,x=\) ?

**Solultion:**

Here, the operation is addition and its inverse operation is subtraction. To solve this equation, subtract 24 from both sides of the equation: \(x+24-24=0-24 \)

Then simplify: \(x+24-24=0-24 → x= \ -24 \)

### Example 4:

Solve this equation. \( 3x=15,x=\)?

**Solultion:**

Here, the operation is multiplication (variable x is multiplied by \(3\)) and its inverse operation is division. To solve this equation, divide both sides of equation by \(3\):

\( 3x=15→3x÷3=15÷3→x=5\)
