how to delete string from a particular text to end of line?

Question

For example,

if there is:

hello(abcdef) = 3
good(adss) = 5

then I have to replace these into:

hello
good

Thus I need to delete each line from '(' to right '\n' and replate these into '\n'

Is is possible by using sed or awk?

Using awk:

awk -F '(' '{ print $1 }' file

Using cut:

cut -d '(' -f 1 file

Using sed:

sed 's/(.*//' file
