Simplify 12e -5f-7e + 3f

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

First, let's combine the e terms:
12e - 7e = 5e

Next, let's combine the f terms:
-5f + 3f = -2f

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

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

First, we group the terms with e:
(12e - 7e) - (5f + 3f)
= 5e - 8f

Therefore, the simplified expression is 5e - 8f.

To simplify the expression 12e - 5f - 7e + 3f, follow these steps:

Step 1: Combine the like terms together. Like terms are terms that have the same variables raised to the same power.

In this expression, we have terms with the variable "e" and terms with the variable "f".

Combining the terms with "e", we have 12e - 7e = (12 - 7)e = 5e.

Combining the terms with "f", we have -5f + 3f = (-5 + 3)f = -2f.

Step 2: Write the simplified expression using the combined terms.

Putting both combined terms together, we get 5e - 2f.

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