7(3f−2g)+14(g−f)

Distribute:=(7)(3f)+(7)(−2g)+(14)(g)+(14)(−f)=21f+−14g+14g+−14f

Combine Like Terms:=21f+−14g+14g+−14f=(21f+−14f)+(−14g+14g)=7f

Answer:=7f

Hope this helped. Have a nice day

The answer is 7f because you need to distribute the 7 to the 3f and -2g and the 14 to the g and -f. That gives you 21f-14g+14g-14f so the gs are cancelled out so then you're left with 21f -14f which is equal to 7f.
