To simplify the expression 9g - 7h - 6g + 2h, we can combine like terms. Like terms are terms that have the same variables raised to the same exponents.
First, we combine the terms with the variable 'g'. We add the coefficients of 9g and -6g, which gives us 9g - 6g = 3g.
Next, we combine the terms with the variable 'h'. We add the coefficients of -7h and 2h, which gives us -7h + 2h = -5h.
Therefore, the simplified expression is 3g - 5h.
To simplify the expression 9g - 7h - 6g + 2h, we can combine the like terms by adding or subtracting their coefficients.
Starting with the variables g, we have 9g - 6g. This gives us a result of 3g.
Next, let's look at the variables h. We have -7h + 2h which results in -5h.
Combining the results from the g and h terms, we get the simplified expression 3g - 5h.
So, the correct answer is 3g - 5h.
