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)
