Answer:
h = 9
Explanation:
- 19 = 2(5 - h + 4) + 8 - 3h ( simplify parenthesis )
- 19 = 2(9 - h) + 8 - 3h ← distribute parenthesis by 2 and simplify
- 19 = 18 - 2h + 8 - 3h
- 19 = 26 - 5h ( subtract 26 from both sides )
- 19 - 26 = 26 - 26 - 5h ( simplify )
- 45 = - 5h ( divide both sides by - 5 )
=
h , then
9 = h
