Simplify 8a − 2a.

Question

Simplify 12e − 5f − 7e +3f.

Simplify 9x + 3y − 6 − 5x + 4y −3.

Simplify 9/11z − 4/11z.

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

Answer 1

8a - 2a = 6a

12e - 5f - 7e + 3f = (12e - 7e) + (-5f + 3f) = 5e - 2f

9x + 3y - 6 - 5x + 4y - 3 = (9x - 5x) + (3y + 4y) + (-6 - 3) = 4x + 7y - 9

9/11z - 4/11z = (9z - 4z)/11 = 5z/11

3/10x + 1/6y + 3/10x + 3/6y = (3/10x + 3/10x) + (1/6y + 3/6y) = 6/10x + 4/6y = 3/5x + 2/3y
