Simplifying the expression 2a - 4b + 7 + 8a + 6b - 2, we can combine like terms:
(2a + 8a) + (-4b + 6b) + (7 - 2)
Simplifying further, we have:
10a + 2b + 5
Therefore, the simplified expression is C. 10a + 2b + 5.

Simplify 6/7c - 5/9d - 1/2c + 1/3d.
A. 5/14c - 2/9d
B. 5/9c + 4/12d = 5/9c + 1/3d
C. 5/14c + 2/9d
D. 5/9c - 4/12d = 5/9c - 1/3d
A. 5/14c - 2/9d
B. 5/9c + 4/12d = 5/9c + 1/3d
C. 5/14c + 2/9d
D. 5/9c - 4/12d = 5/9c - 1/3d
To simplify the expression 6/7c - 5/9d - 1/2c + 1/3d, we can combine like terms:
(6/7c - 1/2c) + (-5/9d + 1/3d)
Simplifying further, we have:
(12/14c - 7/14c) + (-15/9d + 3/9d)
Combining the fractions with the same denominators, we have:
5/14c - 12/9d
To simplify the fraction -12/9d, we can divide the numerator and denominator by 3 to get:
-4/3d
Thus, the simplified expression is:
5/14c - 4/3d
Therefore, the correct answer choice is A. 5/14c - 4/3d.
(6/7c - 1/2c) + (-5/9d + 1/3d)
Simplifying further, we have:
(12/14c - 7/14c) + (-15/9d + 3/9d)
Combining the fractions with the same denominators, we have:
5/14c - 12/9d
To simplify the fraction -12/9d, we can divide the numerator and denominator by 3 to get:
-4/3d
Thus, the simplified expression is:
5/14c - 4/3d
Therefore, the correct answer choice is A. 5/14c - 4/3d.
