Question

Find equivalent expressions for the given expressions.

A. 5/6(a - 6) + 1/6(3 - a)

B. (b + 7)4 + 8 - 5b

Answer 1

A. 5a/6-5+1/2-a/6 = 2a/3-9/2

B. 4b+28+8-5b = 36-b

Answer 2

To find equivalent equations, you simply have to simplify both of these :)

a)  5/6(a - 6) + 1/6(3 - a)

Simplify.

5/6a - 5 + 1/2 - 1/6a

Add like terms.

(5/6a - 1/6a) + (-5 + 1/2)

Simplify.

4/6a +(-4.5)

Simplify.

2/3a - 4.5

b)  (b + 7)4 + 8 - 5b

Simplify.

4b + 28 + 8 - 5b

Add like terms.

(4b - 5b) + (28 + 8)

Simplify.

-b + 36
