6-71.

Solve these systems of equations using any method. Check each solution, if possible. Homework Help ✎

One strategy to solve this system of equations is to multiply the bottom equation by

so you can eliminate. After finding

, 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 forin the second equation.

Use the Equal Values Method.

Refer to part (a).
