Answer:
no solution
Step-by-step explanation:
when you substitute [tex]y[/tex] for [tex]-2x+4[/tex] the equation is false
how I solved this:
1. substitute [tex]y[/tex] for [tex]-2x+4[/tex]
[tex]6x+3(-2x+4)=-12[/tex]
2. distribute the 3
[tex]6x+-6x+12=-12[/tex]
3. combine like terms
[tex]12=-12[/tex]
this is incorrect because 12 does not equal -12, so there is no solution
