360=-2(2+a)-2a

360 = - 2 (2 + a) - 2 a

a = - 91

Solution steps

360 = - 2 (2 + a) - 2 a

Switch sides

- 2 (2 + a) - 2 a = 360

Expand

- 2 (2 + a) : - 4 - 2 a

- 4 - 2 a - 2 a = 360

Add similar elements:

- 2 a - 2 a = - 4 a

- 4 - 4 a = 360

Move

4

to the right side

- 4 a = 364

Divide both sides by

- 4

a = - 91

178300 + (x + 340125) = 551925

9 x - 21 + 8 x - 3 = 180

y, 5 x - 3 y = 9

3 (x - 4) = 18 + 2 x - 11
