Question

Problem about system of equations. See attachment.

Answer 1

Which part are you having trouble with?

Answer 2

answer is no solution

Answer 3

Kevin, just telling what the answer is doesn't help at all. Try to tell how to do it, not just give the answer.

Answer 4

well which part of the working do u need help with lol

Answer 5

@phuelnora For some intuition on why there isn't a solution, look at what happens when you take the first equation multiplied by 3 and add it to the third equation.

Answer 6

the answer is D, but im not sure how to get there

Answer 7

wait no it's C kevin is right

Answer 8

i dont understand how to solve

Answer 9

Take three times the first equation and add it to the third equation. You'll get 0=48. Since it's impossible for 0=48, that means there are no solutions.

Answer 10

why 3?

Answer 11

Because that's how you eliminate the variables. It's just solving using the elimination method.
