`\bold{(2)/(5)x+(3)/(5)x+6-9}`

Combine Similar Elements:
`\bold{(2)/(5)x+(3)/(5)x=x}`

`\bold{x+6-9}`

Subtract:
`\bold{6-9=-3}`

`\bold{x-3}`

Answer 2

This can be written as the expression 2/5x + 6 + 3/5x - 9. Combine like terms(2/5x with 3/5x and 6 with -9) 2/5x + 3/5x = 1x or just x and 6 - 9 = -3 so the new expression is x - 3
