I forgot how to do this. - 2 (21+2y/5) + y=-8

Find y.

-2 (21+2y/5) + y=-8

-42-4y/5+y = - 8

-42-4y+5y/5=-8

-42+y/5=-8

-5*42+5*y/5=-5*8

-210+y=-40

y=-40+210

y = 170

Check

-2 (21+2 (170) / 5) + 170=-8

-2 (21+340/5) + 170=-8

-2 (21+68) + 170=-8

-2 (89) + 170 = - 8

-178 + 170 = - 8

-8 = - 8
