5x + 7 = -3 - 9

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

Answer as fraction: x = \(- \frac{19}{5}\)
