Question

Simplify the expressions below
1. 2(n + 5)
2. 12(x + 5- 3y
3 -(a – 4 + 6b)

Answer 1

1. 2n + 10

2. 12x + 60 - 36y

3. -a + 4 - 6b

Explanation:

1) Distribute the 2.

2(n) + 2(5)

= 2n + 10

2) Distribute the 12.

12(x) + 12(5) + 12(-3y)

= 12x + 60 - 36y

3) Distribute the negative sign.

note: a single negative sign is the same as -1

a(-1) + -4(-1) + 6b(-1)

= -a + 4 - 6b

hope this helps!
