1. Simplify both sides
−6n=−5−5n
−6n=−5+−5n
−6n=−5n−5
2. Add 5n to both sides
−6n+5n=−5n−5+5n
−n=−5
3. Divide both sides by -1.
−n
/−1
=
−5
/−1
n=5
So the variable n, is equal to 5
Answer:
9/2 or 4 1/2 its the 4th one (:
Step-by-step explanation:
Answer:
On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?
That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)
Step-by-step explanation:
x=0, y=-2
