10d=-10d-8(-2d-9)

10 d = - 10 d - 8 (- 2 d - 9)

d = 18

Solution steps

10 d = - 10 d - 8 (- 2 d - 9)

Expand

- 8 (- 2 d - 9) : 16 d + 72

10 d = - 10 d + 16 d + 72

Add similar elements:

- 10 d + 16 d = 6 d

10 d = 6 d + 72

Move

6 d

to the left side

4 d = 72

Divide both sides by

4

d = 18

\frac{6}{5} w = 3 - 3 (\frac{1}{2} w + \frac{3}{2})

y, \frac{y}{3} = x

x + 2 = 16 - 3 x

1 - 4 a = - 18

x, 4 x - 2 y = 1
