Solve -7(11-4w)-15w=-27-(50-13w) show work

• algebra -

-7 ( 11 - 4w ) - 15 w = -27- ( 50 - 13 w ) =

- 7 * 11 + 28 w - 15 w = - 27 - 50 + 13 w

( Remark : -7 * - 4 w = 28 w

- ( -13 w ) = 13 w )

-77 + 28 w - 15 w = - 27 - 50 + 13 w

28 w - 15 w - 13 w = - 27 - 50 + 77

0 = - 77 + 77

0 = 0

All values of w are solutions.
