Solve the system by finding the reduced row-echelon form of the augmented matrix.
x-4y-2z=2
2x-11y-10z=13
-x+6y+6z=-8

If there is one solution, give its coordinates in the answer spaces below. If there are infinitely many solutions, enter t in the answer blank for z, enter a formula for yy in terms of tt in the answer blank for y and enter a formula for x in terms of tt in the answer blank for x. If there are no solutions, leave the answer blanks for x, y and z empty.

Therefore the solution are

x=-6t-10

y=-3-2t

z=t

Step-by-step explanation:

Given system of the equation is

x-4y -2z=2

2x-11y-10z=13

-x+6y+6z=-8

Transforming matrix of the reduce row echelon form

add -2 times the first row to the second row

add 1 times the row to the third row

multiply the second row by

add -2 times the second row to the third row

add 4 times the second row to the first row

The reduce form of the system of equation is

x+0.y+6.z=-10......(1)

0.x+y+2z=-3.........(2)

There are infinity of many solution

z= t (say)

Putting the value of z in the equations of (1) and (2)

x +6t=-10

⇒x=-6t-10

and

y+2t=-3

⇒y= -3-2t

Therefore the solution are

x=-6t-10

y=-3-2t

z=t

step-by-step explanation:

i have no idea

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
