Answer 1

Do you know how to solve these systems by elimination, substitution, or graphing?

Answer 2

I would suggest that elimination is the obvious approach for this one — try multiplying the first equation by 5, the second equation by 2, and adding the resulting equations together, which should give you an equation only in terms of x.
