The first expression can be simplified by combining like terms:
3x + 8y - 5x - 6y= (3x - 5x) + (8y - 6y)= -2x + 2y
The second expression can be simplified by first distributing the negative sign:
16c + (2c - 2) - (9c + 5)= 16c + 2c - 2 - 9c - 5= 16c + 2c - 9c - 2 - 5= 9c - 7
Therefore, the simplified form of the original expressions are:
3x + 8y - 5x - 6y = -2x + 2y16c + (2c - 2) - (9c + 5) = 9c - 7
The first expression can be simplified by combining like terms:
3x + 8y - 5x - 6y
= (3x - 5x) + (8y - 6y)
= -2x + 2y
The second expression can be simplified by first distributing the negative sign:
16c + (2c - 2) - (9c + 5)
= 16c + 2c - 2 - 9c - 5
= 16c + 2c - 9c - 2 - 5
= 9c - 7
Therefore, the simplified form of the original expressions are:
3x + 8y - 5x - 6y = -2x + 2y
16c + (2c - 2) - (9c + 5) = 9c - 7
