-2x-7(x-3)=111

- 2 x - 7 (x - 3) = 111

x = - 10

Solution steps

- 2 x - 7 (x - 3) = 111

Expand

- 7 (x - 3) : - 7 x + 21

- 2 x - 7 x + 21 = 111

Add similar elements:

- 2 x - 7 x = - 9 x

- 9 x + 21 = 111

Move

to the right side

- 9 x = 90

Divide both sides by

- 9

x = - 10

15 x + 5 = 17 x - 1

4 - \frac{1}{2} c = \frac{1}{4} (3 - c) + \frac{1}{8} c

22 (g - 1) = 2 g + 8

- 2 (8 - x) + 6 = - 20

y = - 1^{2} - 1
