Answer :
To write the sentence as an equation, let's follow these steps:
1. Identify the unknown value: The unknown number is represented by [tex]\( m \)[/tex].
2. Translate the words into mathematical symbols:
- The phrase "139 is equal to" translates to [tex]\( 139 = \)[/tex].
- The phrase "392 less than [tex]\( m \)[/tex]" translates to [tex]\( m - 392 \)[/tex].
3. Combine the parts: Putting it all together, the sentence "139 is equal to 392 less than [tex]\( m \)[/tex]" can be written as the equation:
[tex]\[
139 = m - 392
\][/tex]
4. Solve for [tex]\( m \)[/tex]:
- To find the value of [tex]\( m \)[/tex], you need to isolate [tex]\( m \)[/tex] on one side of the equation. To do this, add 392 to both sides of the equation:
[tex]\[
139 + 392 = m
\][/tex]
- Simplify the left side:
[tex]\[
531 = m
\][/tex]
So, the value of [tex]\( m \)[/tex] is 531.
