Step-by-step explanation:

Next time, please share the possible answer choices. Thank you.

"three minus the difference of a number and one"

can be represented algebraicallyl as   3 - (n - 1), where n is the number.

"one-half of the difference of three times the same number and four” can be represented by (1/2)(3n - 4).

The desired equation is thus:

3 - (n - 1) = (1/2)(3n - 4)

1. 34

2. 268

3. x=14.4
