# Translate Phrases into an Algebraic Statement To solve some algebra problems, sometimes you need to translate phrases into algebraic statements then solve the problem

## Step by step guide to translating phrases into an algebraic Statement

Translating key words and phrases into algebraic expressions:

• Addition: plus, more than, the sum of, etc.
• Subtraction: minus, less than, decreased, etc.
• Multiplication: times, product, multiplied, etc.
• Division: quotient, divided, ratio, etc.

### Example 1:

Write an algebraic expression for this phrase “$$12$$ times the sum of $$5$$ and $$x$$”.

Solution:

Sum of $$5$$ and $$x: 5 \ + \ x$$. Times means multiplication. Then: $$12 \ × \ (5 \ + \ x)$$

### Example 2:

Write an algebraic expression for this phrase. “Nine more than a number is $$18$$”

Solution:

More than mean plus, a number $$=x$$
Then: $$9 \ + \ x=18$$

### Example 3:

Write an algebraic expression for this phrase. “Eight more than a number is $$20$$”

Solution:

More than mean plus, a number $$=x$$
Then: $$8+x=20$$

### Example 4:

Write an algebraic expression for this phrase. “$$5$$ times the sum of $$8$$ and $$x$$”

Solution:

Sum of $$8$$ and $$x: 8+x$$. Times means multiplication. Then: $$5×(8 +x)$$

## Exercises

### Write an algebraic expression for each phrase.

• A number increased by forty–two.
