All the distributive property says is a(b+c)=ab+ac take the factor on the outside and multiply on all terms by it on the inside the ( ). so -2(a-8)=?
anonymous

-16

-2(a-8) multiply every term inside the ( ) by -2 so you have -2*a-2(-8) -2a+16

so rewrote your equation as: -2a+16+6a=36
freckles

now combine like terms on the left hand side
freckles
  • freckles
so you ask yourself what is -2a+6a or 6a-2a (since these are the same value)?

ok so you still have -2a+16+6a=36 -2a+6a=36-16 -2a+6a=20 or 6a-2a=20 if you reorder the left hand side
freckles

6-2=?
anonymous
  • anonymous
4

  • freckles
right so 6a-2a=(6-2)a=4a
freckles
  • freckles
\[4a=20\]

now you finally get to see how everyone is getting a=5
