Simplify 12e − 5f − 7e +3f

To simplify 12e - 5f - 7e + 3f, combine like terms:

(12e - 7e) + (-5f + 3f)

Simplifying, we have:

5e - 2f

I apologize for the mistake. Let's simplify again,

9x + 3y − 6 − 5x + 4y − 3

Group the like terms:

(9x - 5x) + (3y + 4y) - (6 + 3)

Combine the coefficients:

4x + 7y - 9

Therefore, the simplified expression is 4x + 7y - 9.

To simplify 9/11z - 4/11z, we combine the fractions with the same denominator:

(9/11z) - (4/11z)

Since the denominators are the same, we can subtract the numerators directly:

(9 - 4)/11z

Simplifying further:

5/11z

Therefore, the simplified expression is 5/11z.

To simplify 3/10x + 1/6y + 3/10x + 3/6y, we first group the like terms:

(3/10x + 3/10x) + (1/6y + 3/6y)

Next, we add the numerators together:

(6/10x) + (4/6y)

To add these fractions, we need to find a common denominator. In this case, the least common multiple (LCM) of 10 and 6 is 30. So, we can rewrite the fractions with the common denominator of 30:

(18/30x) + (20/30y)

Now, we can add the fractions:

18/30x + 20/30y

Finally, we can simplify the fractions by reducing them to their lowest terms. The greatest common divisor (GCD) of 18 and 30 is 6, so we divide both the numerator and denominator by 6:

(18/6)/(30/6)x + (20/30)y

This simplifies to:

(3/5)x + (2/3)y

Therefore, the simplified expression is (3/5)x + (2/3)y.

Simplify 9x + 3y − 6 − 5x + 4y −3.

Thats wrong

Simplify 9/11z − 4/11z.

Simplify 3/10x + 1/6y + 3/10x + 3/6y. Be sure to reduce any fractions to the lowest terms.

Simplify 4x + 8x using the properties of operations.

To simplify 4x + 8x, we can combine the like terms:

4x + 8x = (4 + 8)x

Simplifying further:

12x

Therefore, the simplified expression is 12x.
