Question

-[-(3x-5)+x] for x = -9
step by step please thanks

Answer 1

-[-(3x-5)+x]

Simple substitute in your value of x=-9

-[-(3x-5)+-9]
= -[-3x+5-9]
= -[-3x-4]
= [3x+4]

When you see a negative outside a bracket assume you are multiplying every term in the bracket by -1.

Answer 3

3x+4. Sorry. Ignore my square brackets.

Answer 7

Oh, MY BAD. I'm sorry.
= -[-((3x-9)-5)-9]
= -[-((-27)-5)-9]
= -[-(-32)]
= -32
