If the equation is solved, which is true? (Round to the nearest tenth as needed)
A
If 3 - n = 13, then n = 16.0
B
If 3 + n = 13, then n = 10.0
С
If n + 3 = 13, then n = 4.33333...
D
If 3 + n = 13, then n = 16

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

8/k
