b=2-(2b-4)/3

b = 2 - \frac{2 b - 4}{3}

b = 2

Solution steps

b = 2 - \frac{2 b - 4}{3}

Multiply both sides by

3

3 b = 6 - (2 b - 4)

Expand

6 - (2 b - 4) : - 2 b + 10

3 b = - 2 b + 10

Move

2 b

to the left side

5 b = 10

Divide both sides by

5

b = 2

x, z = 3 x - 2 x y

3 D^{3} y - 4 D^{2} y - 5 Dy + 3 y = 0

x, x + 5 y = 14

12 - x = 8

9 x - 3 = 0
