x+3+\frac{4}{3}\left(x+1\right)=8
Multiply both sides of the equation by 4.
x+3+\frac{4}{3}x+\frac{4}{3}=8
Use the distributive property to multiply \frac{4}{3} by x+1.
\frac{7}{3}x+3+\frac{4}{3}=8
Combine x and \frac{4}{3}x to get \frac{7}{3}x.
\frac{7}{3}x+\frac{9}{3}+\frac{4}{3}=8
Convert 3 to fraction \frac{9}{3}.
\frac{7}{3}x+\frac{9+4}{3}=8
Since \frac{9}{3} and \frac{4}{3} have the same denominator, add them by adding their numerators.
\frac{7}{3}x+\frac{13}{3}=8
Add 9 and 4 to get 13.
\frac{7}{3}x=8-\frac{13}{3}
Subtract \frac{13}{3} from both sides.
\frac{7}{3}x=\frac{24}{3}-\frac{13}{3}
Convert 8 to fraction \frac{24}{3}.
\frac{7}{3}x=\frac{24-13}{3}
Since \frac{24}{3} and \frac{13}{3} have the same denominator, subtract them by subtracting their numerators.
\frac{7}{3}x=\frac{11}{3}
Subtract 13 from 24 to get 11.
x=\frac{11}{3}\times \frac{3}{7}
Multiply both sides by \frac{3}{7}, the reciprocal of \frac{7}{3}.
x=\frac{11\times 3}{3\times 7}
Multiply \frac{11}{3} times \frac{3}{7} by multiplying numerator times numerator and denominator times denominator.
x=\frac{11}{7}
Cancel out 3 in both numerator and denominator.
