Simplify 12e − 5f − 7e +3f .

Answer 1

To simplify the expression 12e − 5f − 7e +3f, we can combine like terms.

The terms 12e and -7e can be combined because they have the same variable and exponent. When we combine them, we get 12e - 7e = 5e.

Similarly, the terms -5f and 3f can be combined because they have the same variable and exponent. When we combine them, we get -5f + 3f = -2f.

Therefore, the simplified expression is 5e - 2f.
