Question

Simplify the expression below.

–(–7y + 12)

Answer 1

You know what a negative sign outside parentheses does?
It changes the signs of every term inside... like so...

for example...
\[\Large -(-9z + 2)\]
\[\Large \color{red}+9z \color{red}-2\]

\[\Large \color{blue}{9z -2}\]

Answer 2

so the answer is 7y - 12 right?

Answer 3

Correct :)

Answer 4

thank you(:
