Answer:
[tex]x=-2\frac{5}{7}[/tex]
Step-by-step explanation:
[tex]19+7x\\[/tex]
Subtract 19 both sides.
[tex]19-19+7x=-19\\0+7x=-19\\7x=-19[/tex]
Divide 7 on both sides to isolate x.
[tex]\frac{7x}{7}=\frac{-19}{7}[/tex] --> [tex]x=-\frac{19}{7}[/tex]
Transform form improper to proper form.
[tex]-\frac{19}{7}=-2\frac{5}{7}\\x=-2\frac{5}{7}[/tex]
