write an algebric expression using x as the variable. 3 fewer than twice a number
2x - 3
what is
2x-3?
To write an algebraic expression for "3 fewer than twice a number" using x as the variable, you can follow these steps:
1. Start with the phrase "a number," which is represented by the variable x.
2. Then, multiply this number by 2 to get "twice a number": 2x.
3. Finally, subtract 3 from this result to get "3 fewer than twice a number": 2x - 3.
Therefore, the algebraic expression using x as the variable is 2x - 3.
