\\ \rm\Rrightarrow 3(x-4+b)=8

\\ \rm\Rrightarrow 3x-12+3b=8

\\ \rm\Rrightarrow 3x+3b=20

\\ \rm\Rrightarrow x+b=20/3

\\ \rm\Rrightarrow x=20/3-b

Step-by-step explanation:

3\left(x-4+1\cdot \:b\right)=8

\mathrm{Divide\:both\:sides\:by\:}3

\frac{3\left(x-4+1\cdot \:b\right)}{3}=\frac{8}{3}

\mathrm{Simplify}

x-4+b=\frac{8}{3}

\mathrm{Subtract\:}b\mathrm{\:from\:both\:sides}

x-4+b-b=\frac{8}{3}-b

\mathrm{Simplify}

x-4=\frac{8}{3}-b

\mathrm{Add\:}4\mathrm{\:to\:both\:sides}

x-4+4=\frac{8}{3}-b+4

\mathrm{Simplify}

x=-b+\frac{20}{3}
