its the same question

Answer 14

Answer 15

same thing for subtraction, but don't forget parentheses and the distributive law
\[2x-5-(1-x)=2x-5-1+x=3x-6\]

Answer 16

multiply means multiply, so write
\[(2x-5)(1-x)\] and multiply out ( or just leave it in factored form)

and divide means divide so you get
\[\frac{2x-5}{1-x}\]
