Solve these systems of equations using any method. Check each solution, if possible.
One strategy to solve this system of equations is to multiply the bottom equation by
so you can eliminate.
, plug in its value into one of the equations to find the value of .
Because one of the equations above is already solved for
, one strategy to solve this system is to substitute the first equation in for in the second equation.
Use the Equal Values Method.
