Would I do the same to this one too? http://gyazo.com/bf5a16423e8081a368664618355c96dd

OpenStudy (mertsj):

This one says to solve by substitution.

OpenStudy (anonymous):

How would I do that one?

OpenStudy (mertsj):

Take the third equation and solve it for x and substitute that value into the other two equations.
