Question

What is (1.6x + 7.3) + (–0.6x + 2) – (7.8 – 3.4x), simplified?

(1.6x + 7.3) + (–0.6x + 2) – (7.8 – 3.4x)

1.6x + 7.3 – 0.6x + 2 – 7.8 + 3.4x

1.6x – 0.6x + 3.4x + 7.3 + 2 – 7.8

Answer 1

(1.6x + 7.3) + (–0.6x + 2) – (7.8 – 3.4x)
1.6x + 7.3 – 0.6x + 2 – 7.8 + 3.4x
1.6x – 0.6x + 3.4x + 7.3 + 2 – 7.8
4.4x + 1.5
thats all I guess

Answer 2

`4.4x + 1.5`

Explanation:

`(1.6x + 7.3) + (-0.6x + 2) - (7.8 -3.4x)`

To simplify this we use order of operation PEMDAS

WE start with removing the parenthesis and then we combine like terms

Multiply negative sign inside the third parenthesis

`1.6x + 7.3-0.6x + 2-7.8 +3.4x`

Now we combine like terms

`1.6x-0.6x+3.4x=4.4x`

`7.3+ 2-7.8=1.5`

so simplified expression is
`4.4x + 1.5`
