Answer:
The coefficient of [tex]q[/tex] is [tex]7[/tex]
Step-by-step explanation:
The two expressions are
[tex]23q-34[/tex] and [tex]-16q-r[/tex].
The sum of the two expressions is
[tex]23q-34+-16q-r[/tex]
When we group like terms the expression will be,
[tex]=23q-16q-r-34[/tex]
When we simplify the expression will now be
[tex]=7q-r-34[/tex]
The coefficient of [tex]q[/tex] is the constant behind [tex]q[/tex] in the expression.
The coefficient of [tex]q[/tex] is therefore [tex]7[/tex].
