Question

How do you simplify `3.2 (x + y) + 2.3 (x+y) +4x`?

Answer 1

`9.5x + 5.5y`

Explanation:

First, use the distributive property to simplify `3.2(x+y)` and `2.3(x+y)`:
`3.2x + 3.2y + 2.3x + 2.3y + 4x`

Now color-code the like terms:
`color(red)(3.2x) quadcolor(blue)(+quad3.2y) quadcolor(red)(+quad2.3x) quadcolor(blue)(+quad2.3y) quadcolor(red)(+quad4x)`

Combine like terms:
`9.5x + 5.5y`

Hope this helps!
