Which of the following statements is true?
n = m
n = 4m
The graph of the solution
is parallel lines.
(0, 0) is a solution to n = m
and to n = 4m.
No point on the line num
is also on the line n = 4m.
Every solution to n = m is
also a solution to n = 4m.

(0, 0) is a solution to n = m

Step-by-step explanation:

We have the system of equations:

When we substitute the top equation into the bottom equation, we get:

Subtract m from both sides to get:

Divide through by 3

Or

But we know n=m, therefore n=0.

Therefore (0,0) is a solution to the system.

The true statement is (0, 0) is a solution to n = m

The following information should be considered:

n = m

n = 4m

At the time of substitute the top equation into the bottom equation, we get:

m = 4n

Now subtract m from both the sides

0 = 3m

Now divided it by 3

0 = m

or m = 0

And, n = m

Son the above statement should be true.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
