How do you know when a system is ready for each method?

Groups:

(a) Substitution

,

(b) Elimination

,

(c) Graphing

• There are opposite coefficients for the same variable.

• Both equations are in slope-intercept form.

• x and/or y is isolated in at least one equation

• All the variables are "lined up"

Solve the system.
