Question

Find the solution set
2w+1-(5-w)=3(w-7)

Answer 1

Distribute that - on the left side and distribute that 3 on the right side
\[2w+1-5+w=3w-21\]
Then combine terms on the right\[3w-4=3w-21\]
Cancel the 3w on each side and you get the impossible
\[-4=-21\]
When you get an impossible statement like this the solution set is
"No solution" or "the empty set"

Answer 2
