Answer 1

h - 3

See explanation below

Explanation:

This is not too difficult

We have (- 2h + 1) + (3h - 4) and we are asked to simplify

Expand the brackets:
(- 2h + 1) = - 2h + 1

(3h - 4) = 3h - 4

Add the two:
(- 2h + 1) + (3h - 4) = - 2h + 1 + 3h - 4

Group like terms

- 2h + 3h + 1 - 4

-2h + 3h = h

+1 - 4 = -3

- 2h + 1 + 3h - 4 = h - 3

and therefore

(- 2h + 1) + (3h - 4) = h - 3
