5x + 7 = -3 - 9

First, simplify -3 - 9 to get -12. / Your problem should look like: [tex]5x + 7 = -12[/tex]
Second, subtract 7 from both sides. / Your problem should look like: [tex]5x = -12 - 7[/tex]
Third, simplify -12 - 7 to get -19. / Your problem should look like: [tex]5x = -19[/tex]
Fourth, divide both sides by 5. / Your problem should look like: [tex]x = -\frac{19}{5} [/tex]

Answer as fraction: x = [tex]- \frac{19}{5} [/tex]
Answer as decimal: x = -3.8
