Answer 1

We have
`a=3,b=-2` and expression
`-a+6b`.

To evaluate expression substitute
`a` and
`b` with their values to get
`-3+6\cdot(-2)`. Then simplify the expression starting with multiplication to get
`-3-12` and now simply subtract get value of expression
`\boxed{-15}`.

Hopefully this will help.
