Hey there!
Your answer = [tex](x=7)[/tex]
[tex] \left[\begin{array}{ccc}\boxed{ \frac{3}{7} *x+5-(8)=0 } \\ \\ (Simplify \ \frac{3}{7}) \\ \\ \boxed{(( \frac{3}{7}*x)+5)-8=0} \\ \\ (do \ the \ whole \ fraction \ using \\ (7) \ as \ the \ bottom \ denominator) \\ \\ \boxed{\boxed{5= \frac{5}{1} = \frac{5*7}{7}}} \\ \\ pull \ out \ like \ factors \\ \\ 3x - 21 = 3 * (x - 7) \\ \\ \boxed{ \frac{3*(x-7)}{7}*=0*7} \\ \\ x-7 = 0 \\ \\ add \ seven \ to \ both \ sides \\ \\ (7) \ is \ the \ answer! \end{array}\right] [/tex]
I hope this helps you!
