Question

- 1/3(6x+18)=10
Help me find the answer before 7:40

Answer 1

x = -8

Explanation:

`-(1)/(3)\left(6x+18\right)=10`

`\mathrm{Multiply\:both\:sides\:by\:}-3`

`\left(-(1)/(3)\left(6x+18\right)\right)\left(-3\right)=10\left(-3\right)`

`\mathrm{Simplify}`

`6x+18=-30`

`\mathrm{Subtract\:}18\mathrm{\:from\:both\:sides}`

`6x+18-18=-30-18`

`\mathrm{Simplify}`

`6x=-48`

`\mathrm{Divide\:both\:sides\:by\:}6`

`(6x)/(6)=(-48)/(6)`

`\mathrm{Simplify}`

`x=-8`
