Answer 2

{3х+4у+5z=22
{x-6y-6z=-9
{2x+4y-4z=10          |:2     

{3x+4y+5z=22
{x= -9+6y+6z
{x+2y-2z=5

{3(-9+6y+6z) +4y+5z=22
{(- 9+6y+6z)  +2y -2z=5

{-27 +18y+18z +4y +5z=22
{-9 +8y+4z=5

{22y  + 23z= 22+27
{8y+4z=5+9                   |:4

{22y +23z =49
{2y +z= 3.5

{22y+23z=49
{z=3.5-2y

22y +23(3.5-2y)=49
22y +80.5 - 46y=49
-24y= 49-80.5
-24y= -31.5
y= (-31.5) : (-24)
у= 1,3125

z= 3.5  - 2 *1.3125
z= 3.5- 2.625
z=0.875

x= -9 +6*1.3125 +6*0.875
x=-9 + 7.875+ 5.25 
x= 13.125-9
x=4.125

проверим:
3*4,125 +4*1,3125+5*0,875= 12,375+5,25+4,375=22
4,125-6*1,3125 -6*0,875 = 4,125-7,875-5,25= -9
2*4,125 +4*1,3125 -4*0,875 = 8,25 +5,25 - 3,5 =10

Ответ: х=4,125  ;  у= 1,3125 ;  z=0, 875 .

Answer 3

Solving the System of Equations

To solve the system of equations, we'll start by examining the provided equations and then proceed with the solution.

Given Equations: 1. Equation 1: *Unknown content*2. Equation 2: *Unknown content*3. Equation 3: *Unknown content*4. Equation 4: *Unknown content*5. Equation 5: *Unknown content*6. Equation 6: *Unknown content*7. Equation 7: *Unknown content*8. Equation 8: *Unknown content*9. Equation 9: *Unknown content*10. Equation 10: *Unknown content* Unfortunately, the content of the equations is not provided, making it impossible to solve the system of equations without the actual equations. If you could provide the specific equations, I'd be more than happy to help you solve them!
