Question

5. What is the value of y in the solution to the systems of linear equations shown below?

Answer 1

Answer:

x=$\frac{60}{121}$,z=$\frac{535}{121}$,y=-10

Step-by-step explanation:

Answer 2

Answer:

$1) \: \: 12x + 6y + 7z = - 35 \\ 6y = - 35 - 12x + 7z \\ y = \frac{ - 35 - 12x + 7z}{6} \\ \\ 2) \: \: 7x - 5y - 6z = 200 \\ - 5y = 200 - 7x + 6z \\ y = \frac{200 - 7x + 6z}{ - 5} \\ \\ 3) \: \: x + y = - 10 \\ y = - 10 - x$
