Answer:
Lina's solution is correct because it expresses 126 as a product of prime factors.
Step-by-step explanation:
Prime factorization can be defined as a methodology of breaking down an original number down into the set of prime numbers which when multiplied together give us the original number.
Prime factorization makes use of a factor tree
The number we are to carry out prime factorization on is 126
126
/\
3 42
/\
6 7
/\
2 3
The Prime Factorization is:
2 x 3 x 3 x 7
Hence, Lina's factor tree of 126. 126 branches to 3 and 42. 42 branches to 6 and 7. 6 branches to 2 and 3. The equation is 126
= 2 times 3 squared times 7.
Is correct.

Answer:
Step-by-step explanation:
The given system of linear equations is:
We have to solve the equations for the values of .
Let us use elimination method in which we eliminate one of the variables from the two variables.
For this, let us multiply the first equation by and second equation by
Now, the equations become:
Now, let us add (1) and (2):
Using the equation:
Putting value of :
So, the answer to the system of linear equations is:
