Answer:
w = - 3
Explanation:
given
- 2w - 23 = 13w + 22 ( subtract 13w from both sides )
- 2w - 13w - 23 = 13w - 13w + 22 ( simplify both sides )
- 15w - 23 = 22 ( add 23 to both sides )
- 15w - 23 + 23 = 22 + 23 ( simplify both sides )
- 15w = 45 ( divide both sides by - 15 )
w =
, that is
w = - 3
