39=2c-3(4c-3)

39 = 2 c - 3 (4 c - 3)

c = - 3

Solution steps

39 = 2 c - 3 (4 c - 3)

Switch sides

2 c - 3 (4 c - 3) = 39

Expand

- 3 (4 c - 3) : - 12 c + 9

2 c - 12 c + 9 = 39

Add similar elements:

2 c - 12 c = - 10 c

- 10 c + 9 = 39

Move

9

to the right side

- 10 c = 30

Divide both sides by

- 10

c = - 3

12 u = 12

\frac{3}{13} = 21

x, 7 x - y = 35
