When solving a system algebraically…<br />
If you end up with an equation that is ______________ true,<br />
4 9<br />
the system has _____________________ (or, it is _________________________ )<br />
or, graphically, the equations’ lines would be ___________________________.<br />
If you end up with an equation that is _________________ true,<br />
-24 = -24<br />
the system has _____________________ (or, it is _________________________ )<br />
or, graphically, the equations’ lines would be ___________________________.<br />
Continue solving these systems algebraically using the substitution method.<br />
