-9x=16-y equation 1
12x=-5-y equation 2
x=-5-y÷12 from equation 2
substitute this x in equation 2
so 
-9(-5-y÷12)=16-y
15+3y=64-4y
7y=49
y=7 
and then substitute this value of y in equation (x=-5-y÷12)
so x= -5-7÷12
     x=-1 
so y=7 and x=-1

Please help and explain. Thank you!

Answer:

For the first question, the answer is 216 and the equation would become just 6^3

For the second, the answer is 9.

Step-by-step explanation:

When there is a negative exponent, that monomial is brought up to the top of the fraction, (the numerator) so 1/6^-3 becomes 1(6^3)/1, or simplified, just 6^3 since divided by one is the same number and times one is the same number. 6 x 6 x 6 is 216.

When there is a negative exponent outside the equation in a <u>fraction,</u> you need to take the reciprocal  of the fraction. Since it's squared, it will always be positive, so we can ignore the negative sign. 3/1 (or just 3) to the power of 2 is 9. (3 x 3 is 9).

When explained throughly this might be found confusing, but it's a very easy concept to get after a while.
