AlekseyPX

Answer:

C. (1, 1, 2)

Step-by-step explanation:

Well plugging them in one by one.

x + y - z = 0

-1 + 2 - 4 = 0

no.... no it doesn't equal 0 so it isn't the solution

-1 + 0 - 2 = 0

nope it doesn't equal 0 so it's also not the solution

1 + 1 - 2 = 0

Yes! this could equal the solution so lets keep going down the line

3x - y + z = 4

(3*1) -1 + 2 = 4

Yes! this also is correct

I could keep talking and talking but yes, (1, 1, 2) is your answer

Hope this helps! <3

Ben's age is currently twice of his sister, Emma. 8 years ago, Ben's age was 2 and a half times that of Emma's age at that time.
Yakvenalex [24]

Emma is now 24 years old then Ben would be 2E, or 48 years old.

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Let B and E be Ben's and Emma's current ages, respectively.

We have given that;

Ben's age is currently twice of his sister, Emma.

B = 2E

and

8 years ago, Ben's age was 2 and a half times that of Emma's age

B-8 = 2.5(E-8)      

We can substitute the value of B from the first equation into the last one

B-8 = 2.5(E-8)

(2E)-8 = 2.5(E-8)

2E-8 = 2.5E- 20

-0.5E = -12

E = 24

Thus, Emma is now 24 years old then Ben would be 2E, or 48 years old.
