wait thats the problem?
16 maybe im not sure
try using the distributive property on -2(a-8) first.
a = 5
hmmm thats the deal i dont under stand how this works im not the biggest on math
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)=?
ok so multiply thes numbers
-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
now combine like terms on the left hand side
so you ask yourself what is -2a+6a or 6a-2a (since these are the same value)?
ok so i got 20 when i added every thing except the letters
oh do you mean you did 36-16 which is 20?
bu the letters are 16 each
a=5 for definate
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
right so 6a-2a=(6-2)a=4a
now you finally get to see how everyone is getting a=5
ohhh ok i get it thatnk you soo much
