Question

Simplify the expression.

Answer 1

`19 - (6)/(5)j`

written out on a computer keyboard, you would type: 19 - (6/5)j

Explanation:

The terms that dont have a 'j' attached to them all group up and combine to this: 18 + (-5) + 6 = 18-5+6 = 13+6 = 19

The rest of the terms have a 'j', and they combine to:
`-(2)/(5)j - (4)/(5)j = \left(-(2)/(5) - (4)/(5)\right)j = (-2-4)/(5)j = -(6)/(5)j`

After combining both sets of like terms, we have 19 as the first result and
`-(6)/(5)j` as the second result. They are then added to get
`19 + \left(-(6)/(5)j\right) = 19 - (6)/(5)j`

We cant simplify any further because there are no like terms left.
