Question

How do you simplify `(2t+4)3+6(-5t)-(-8)`?

Answer 1

`6t-10`

Explanation:

Remove the brackets using the distributive law. Be careful of the signs.

`(2t+4)color(blue)(3)+6(-5t)-(-8)`

=`color(blue)(3)(2t+4)color(red)(+6(-5t))color(lime)(-(-8))" "larr` there are 3 terms

=`color(blue)(6t+12)color(red)(-30)color(lime)(+8)`

=`6t +12+8-30" "larr` re-arrange for easier calculation

=`6t-10`
