6 d - 12 - d = 9 d + 53 + d

d = - 13

Solution steps

6 d - 12 - d = 9 d + 53 + d

Group like terms

6 d - d - 12 = 9 d + 53 + d

Add similar elements:

6 d - d = 5 d

5 d - 12 = 9 d + 53 + d

5 d - 12 = 9 d + d + 53

Add similar elements:

9 d + d = 10 d

5 d - 12 = 10 d + 53

Move

12

to the right side

5 d = 10 d + 65

Move

10 d

to the left side

- 5 d = 65

Divide both sides by

- 5

d = - 13

x, 2 x - \frac{1}{3} y = 4

7 r + 10 - 3 r = 9 r - 5 (r - 2)

- 7 + 9 = - 9 + 7

x = 2 - 2 [2 x - 3 (1 - x)]

lo g_{9} (- 3) = 2
