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)

To combine the terms with "c", we need to find a common denominator:

(12/14c - 7/14c) + (-5/9d + 3/9d)

Simplifying the "c" terms gives us:

5/14c + (-2/9d)

Combining the "d" terms gives us:

(5/14c - 2/9d)

So, the simplified form of 6/7c - 5/9d - 1/2c + 1/3d is 5/14c - 2/9d.

simplify 6/7c - 5/9d - 1/2c + 1/3d

Simplify 2a āˆ’ 4b +7 + 8a + 6b āˆ’ 2.

To simplify the expression 67c - 59d - 12c + 13d, we can combine like terms:

(67c - 12c) + (-59d + 13d)

This gives us:

55c - 46d

So, the simplified form of 67c - 59d - 12c + 13d is 55c - 46d.
