Question

-28=8x+2(x+6) im so lost

Answer 1

`\bf{Swap \ sides \ 8x+2(x+6)=-28 }`

`\bf{Expand \ 2(x+6): \ \ \ \ 2x+12}`

`\mathrm{Set \ the \ variables \ using: \ \ \ a(b+c)=ab+ac}`

`a=2,\:b=x,\:c=6`

`=2x+2\cdot \:6`

`\mathrm{Multiply\:the\:numbers:}\:2\cdot \:6=12`

`=2x+12`

`8x+2x+12=-28`

`\mathrm{Add\:similar\:elements:\:8x+2x=10x}`

`10x+12=-28`

`\mathrm{Subtract\:}12\mathrm{\:from\:both\:sides}`

`10x+12-12=-28-12`

`\mathrm{Simplify}`

`10x=-40`

`\mathrm{Divide\:both\:sides\:by\:}10`

`(10x)/(10)=(-40)/(10)`

`\mathrm{Simplify \ (10x)/(10): \ \ x }`

`\mathrm{Divide:}\:(10)/(10)=1`

`=x`

`\mathrm{Simplify \ (-40)/(10): \ \ -4 }`

`\rm{Apply \ the \ properties \ of \ fractions \ to \ fractions: \ \ (-a)/(b)=-\drac{a}{b}}`

`=-(40)/(10)`

`\rm{split: \ (40)/(10)=4 }`

`\bf{x=-4 \ \ \to \ \ \ Answer }`
