Let n = the unknown number.
Quotient tells you use division.
n/7 = 39
Multiply both sides by 7 to cancel out the number in the denominator and isolate the variable.
n = 39(7) = 273
n = 273
Answer: just line up the decimals.

Answer:
Step-by-step explanation:
There are several ways to solve this quartic equation. But since the coefficients, they repeat a=1,b=2,c=1,d=2, but e=0, and they are multiple of each other, then it is more convenient to work with factoring as the method of solving it.
As if it was a quadratic one.
