Question

Solve for x:
3(x-4+1b)=8

Answer 1

`\\ \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`

Answer 2

Explanation:

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

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

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

`\mathrm{Simplify}`

`x-4+b=(8)/(3)`

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

`x-4+b-b=(8)/(3)-b`

`\mathrm{Simplify}`

`x-4=(8)/(3)-b`

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

`x-4+4=(8)/(3)-b+4`

`\mathrm{Simplify}`

`x=-b+(20)/(3)`
