let's solve the inequality:
[tex]-12>7x+4[/tex]
then we can substract 4 from both sides of the inequality, and obtain:
[tex]-12-4>7x[/tex]
solving the subtraction
[tex]-16>7x[/tex]
then, we divide on both sides of the inequality by 7
[tex]-\frac{16}{7}>x[/tex]
and the graph of this inequality would be:
