Question

1. write an equvialent expression: -1/2 (-2x + 4y)

2. Factor to write an equivalent expression: 26a - 10.

Answer 1

1. x - 2y
2. 2(13a - 5)

In-depth explanation:

We're asked to simplify the expression -1/2(-2x + 4y).

To simplify, simply distribute -1/2:

-1/2(-2x + 4y)

x - 2y

--------

Factor out the GCF of the expression 26a - 10 by dividing both terms by 2:

2(13a - 5)

Answer 2

1) x-2y 2) 2(13a-5)

Explanation:

1) -1/2(-2x+4y)=2/2x-4/2y=x-2y

2) 26a-10=2(13a-5)
