Investigate the structure of each equation to determine the best method to use to solve this system?

y = 6x − 11

−2x − 3y = −7

• Graphing because both equations are in slope-intercept form.

• Substitution because a variable is isolated.

• Elimination because both equations are in standard form with like terms "lined up".
