To simplify the expression ( 2c – 3 – 5c + 7 + 9c – c ), follow these steps:
1. Combine like terms:
– For the ( c ) terms: ( 2c – 5c + 9c – c )
– Combine: ( (2 – 5 + 9 – 1)c = 5c )
– For the constant terms: ( -3 + 7 )
– Combine: ( -3 + 7 = 4 )
2. Put it all together:
– The simplified expression is ( 5c + 4 ).
Therefore, the correct answer is 5c + 4.
