Simplify 9g - 7h - 6g + 2h
A. 3g - 5h
B. -2gh
C. 2gh - 4gh
D. 3g + 5h
To simplify 9g - 7h - 6g + 2h, combine like terms by adding the coefficients of the g terms and the coefficients of the h terms:
9g - 6g - 7h + 2h = (9g - 6g) + (-7h + 2h) = 3g - 5h
The simplified expression is 3g - 5h.
Therefore, the answer is A. 3g - 5h.
