Question

Реши систему : { z = 8 + y { z - 2y +2 = 5 Ответ: z = y =

Answer 1

ответ:

$\displaystyle (y,z)=(5,13)$

решение: метод подстановки

$\displaystyle \left \{ {{z=8+y} \atop {z-2y+2=5}} \right.\\ \\8+y-2y+2=5\\y=5\\z=8+5\\z=13$

Answer 2

Solving the System of Equations

To solve the given system of equations:

z = 8
y + z - 2y + 2 = 5

Let's substitute the value of z into the second equation:

y + 8 - 2y + 2 = 5

Simplifying the equation, we get:

-y + 10 = 5

Now, let's isolate y by subtracting 10 from both sides:

-y = -5

Multiplying both sides by -1, we get:

y = 5

Finally, let's substitute the value of y back into the first equation to find the value of z:

z = 8

Therefore, the solution to the system of equations is:

z = 8
y = 5

Note: The provided search snippet does not directly address the given system of equations. However, the solution can be obtained by solving the equations algebraically.
