Question

Rewrite each linear expression by factoring out the greatest common factor. (please solve each question)

1. -5y - 35

2. 54n - 81

Answer 1

1. y + 7

2. 2n - 3

Explanation:

1. First break up the equation.

-5y -35

The GCF of -5y and -35 is -5.

Divide by -5.

-5y ÷ (-5) = y

-35 ÷ (-5) = 7

Add together.

y + 7

2. Do the same as in question 1.

54n -81

GCF = 27

54n ÷ 27 = 2n

-81 ÷ 27 = -3

Add together.

2n - 3
