Add like terms and then isolate #b#

Solving implies you find the value of the variable.

In this case, add like terms first.

#9b-2b=14#

#7b=14#

Now we isolate #b#.

#(7b)/7=14/7#

#b=2#

We can check our work by subbing in #b=2# into the original equation.

#9b-2b=14#

#9(2)-2(2)=14#

#18-4=14#

#14=14#

Thus, we are correct.

Hope this helps :)
