Which equation matches the sentence? Column A Column B

1. Seven more than 2 times a number is 23.

2. The difference of 2 times a number and 7 is 23.

3. The sum of 7 times a number and 2 is 23.

4. Seven less than 2 times a number is 23.

a. 7n 2 = 23

b. 2n - 7 = 23

c. 2n 7 = 23

I will put an equation to the corresponding number.

1) Seven more than 2 times a number is 23 = > 2n + 7 = 23

2) The difference of 2 times a number and 7 is 23 = > 2n - 7 = 23

3) The sum of 7 times a number and 2 is 23 = > 7n + 2 = 23

4) Seven less than 2 times a number is 23 = > 2n - 7 = 23

Based on the choices. The equation that matches sentences 2 & 4 is letter b. 2n - 7 = 23

Though both sentences are structured differently and used different terms, they both refer to subtraction of 7 from the product of 2 and n to get the difference of 23.
