Simplify 12e−5f−7e+3f .

Answer 1

To simplify the expression \( 12e - 5f - 7e + 3f \), we can combine like terms.

1. Combine the \( e \) terms: \[ 12e - 7e = (12 - 7)e = 5e \]

2. Combine the \( f \) terms: \[ -5f + 3f = (-5 + 3)f = -2f \]

Putting it all together, we have: \[ 5e - 2f \]

Thus, the simplified form of \( 12e - 5f - 7e + 3f \) is \( 5e - 2f \).
