Answer:
The system is inconsistent.
Step-by-step explanation:
The system is
The associated matrix to the system is
Now we use row operations to find the echelon form of the matrix:
1. We substract to row 2, two times the row 1.
We substract to row 3, three times the row 1.
We substract to row 4, four times the row 1 and obtain the matrix
2. We multiply the second row of the preview step by -1/4. We obtain the matrix
3.
We add to row 3, eight times the row 2.
We add to row 4, fourtheen times the row 2 and obtain the matrix
4. We add to row 4 of the preview step, five times the row 3 and obtain the matrix
Using backward substitution we have that
, then
and this is absurd. Then The system is inconsistent.
X + 4 = 12
This is because the question gives you everything you require for this sentence to be formed. 12 is the final answer. 4 is added on and
is basically the number that is to be found.

Answer:
Step-by-step explanation:
Given: Hector saved twice as much money as Sam.
Ted saved $100 more than Hector.
Gina saved $50 less than Ted.
As given, lets assume the amount of money Sam has in saving be "x".
Now, finding saving of each person given.
Writing the algebric expression of each´s saving amount.
we know, Hector saved twice as much money as Sam.
∴ Hector saving=
Also, Ted saved $100 more than Hector.
∴ Ted´s saving=
Next finding Gina´s saving
As given, Gina saved $50 less than Ted.
∴ Gina´s saving=
Opening parenthesis and solving it.
⇒ Gina´s saving=
Algebric expression of Gina´s saving=
