2x=2-9

21y=4-6x

2x=-7

6x=4-21y

x=-7/2

6(-7/2)=4-21y

-21=4-21y

-21-4=-21y

-25=-21y

y=-25/-21

:.y=1 4/21.

Which expression is equivalent to (7 – 3k) – (4 – 5k) – (6 – 2k)?

gladu [14]

Answer:

The right response is " $3(k-1)$ ". A further solution is given below.

Step-by-step explanation:

The given expression is:

⇒ $(7 -3k) - (4 - 5k) - (6 - 2k)$

On solving the above expression, we get

⇒ $7-3k-4+5k-6+2k$

⇒ $7-3k-10+7k$

⇒ $3k-3$

On taking "3" as common, we get

⇒ $3(k -1 )$

How to solve this system of equal: x+y+z=1;x^2+y^2+z^2=1

swat32

There are infinitely many solutions.

Algebraically, we can eliminate $z$ and try to solve for $x,y$ :

$x+y+z=1\implies z=1-x-y$

Then

$x^2+y^2+(1-x-y)^2=1$

$\implies x^2+y^2+1-2x+x^2-2y+y^2+2xy=1$

$\implies x^2-x+y^2-y+xy=0$

which is the equation of an ellipse.
