<h2>Translating Words into Equations</h2>
We can translate words into numerical equations by replacing certain key words with numbers or operations:
- <em>twice</em> = multiply by 2
- <em>difference</em> = subtract
- <em>a/the number</em> = Let this be <em>x</em>
- <em>sum</em> = add
We're given:
- Twice the difference of a number and 3 is equal to three times the sum of the number and 2
Translate into an equation:
- <u>Twice</u> the <u>difference</u> of <u>a number </u>and 3 is equal to three times the <u>sum</u> of<u> the number</u> and 2
⇒
x = -12
