Answer:
[tex]x = - \frac{2}{5} [/tex]
alternative form:
[tex]x = - 0.4[/tex]
Step-by-step explanation:
[tex] - 4 + 5(x + 3) = 9 \\ first \: you \: need \: to \: distribute \\ \\ - 4 + 5x + 15 = 9 \\ subtract \: 15 \: from \: both \: sides \\ \\ - 4 + 5x = - 6 \\ add \: 4 \: from \: both \: sides \\ \\ 5x = - 2 \\ divide \: both \: sides \: by \: 5 \\ \\ x = - \frac{2}{5} [/tex]
