Question

Solve the equation -21 + 25n = 14 for n.

A. 1/4
B. 1/3
C. 4/3
D. 7/5

Answer 1

D. 7/5

Explanation:

To solve -21 + 25n = 14 for n, you must first isolate the variable.To do this add 21 on each side of the equation, 21+-21 cancels out and 21 + 14 equals 35.

You now have 25n = 35. To then further isolate the variable, divide each side by 25.25 and 25 cancels out so you get n = 1.4.

7/5 is equal to 1.4

So it is D!!!!!!!!!!!!!

Answer 2

Answer D: 7/5

Explanation:

Combine like terms: add 21 to both sides, obtaining:

25n = 35, or n = 35/25, or n = 7/5 (Answer D)
