What is (w-4/9)(-2/3)=-4/5
pshichka [43]
<span>(-2/3)*(w-(4/9)) = -4/3 // + -4/3

(-2/3)*(w-(4/9))-(-4/3) = 0

(-2/3)*(w-4/9)+4/3 = 0

4/3-2/3*(w-4/9) = 0

(-2/3*3*(w-4/9))/3+4/3 = 0

4-2/3*3*(w-4/9) = 0

44/9-2*w = 0

(44/9-2*w)/3 = 0

(44/9-2*w)/3 = 0 // * 3

44/9-2*w = 0

44/9-2*w = 0 // - 44/9

-2*w = -44/9 // : -2

w = -44/9/(-2)

w = 22/9

w = 22/9</span>

Solve the following 3 × 3 system. Enter the coordinates of the solution below.
defon

9514 1404 393

Answer:

  (x, y, z) = (-1, 0, -3)

Step-by-step explanation:

We notice that the coefficients of z are such that elimination of the z term from the equations is made easy.

Adding equations 1 and 2:

  (2x -3y -2z) +(x +3y +2z) = (4) +(-7)

  3x = -3

  x = -1

Adding equations 2 and 3:

  (x +3y +2z) +(-4x -4y -2z) = (-7) +(10)

  -3x -y = 3

Substituting for x, we get ...

  (-3)(-1) -y = 3

 0 = y . . . . . . . . . . . add y-3 to both sides

Then z can be found from any equation. Substituting for x and y in the second equation gives ...

  -1 +2z = -7

  2z = -6 . . . . . add 1

  z = -3 . . . . . .divide by 2

The solution is (x, y, z) = (-1, 0, -3).
