Question

What is the value of the expression (3a-b)/(6(b+a)) when a = 4 and b = -2? Show your work to support your answer.

please be specific

Answer 1

`1(1)/(6)` or 1.166 Repeating

Explanation:

This is a very simple equation!

First you write it out

`(3a-b)/(6(b+a))`

Now you plug in your values.

a = 4

b= -2

So.

`(3(4) - (-2))/(6(-2+4))`

Now, follow PEMDAS

3 (4) = 12

12 - (-2) is the same as 12+2 Which equals 14

Now you have...

`(14)/(6(-2+4))`

-2 + 4 = 2

6 (2) = 12

Final Fraction is

`(14)/(12)`

Which can be reduced to

`(7)/(6)`

or

1.166 (repeating)

Hope this helps!
