Question

please help will give medal! what is the value of a? 9a-3(a-6)= -6

Answer 1

First get rid of your parenthesis

Answer 2

9a-3a-6= -6 ?

Answer 3

You have to multiply everything in the parenthesis by -3, so try again

Answer 4

i dont get it

Answer 5

I'll show you

Answer 6

You have to distribute the -3 to the insides of the parenthesis by multiplication for them to be taken away.
your equation is:\[9a-3(a-6)=-6 \]
so by distributing and multiplying everything in the parenthesis, you will end up with:
\[9a-3a+18=-6\]

Answer 7

ohh okay

Answer 8

Now subtract 3a from 9a, then after you do that subtract 18 from both sides, then divide both sides by 6

Answer 9

so after the subtracting would it be 6a+18= -6?
