The algebraic expression given is 3x + 7 – 10. To understand this expression, we need to simplify it first.
By combining the constant terms, we can simplify 7 – 10 to get -3. So, the expression can be written as:
3x – 3
This means that the phrase that matches the algebraic expression describes a situation where you have three times a variable x and then subtract three from it. In a more verbal form, this could be expressed as:
- Three times a number decreased by three
- Three multiplied by a variable and then reduced by three
In either case, the essence of the expression revolves around taking three times some variable and then subtracting a constant.
