Answer:

i think

you multiply second equation by 2

12x-8y=12

12x+8y= -60

then you add

which is

24x=72

then you do 24 ÷24

and 72÷24 which is 3

so x is 3

then substitute x

so 12x(3) +8y=12

36+8y=12

then 8y - 8 and 12-8

so 36÷36 and 4÷36

so y is 9

A zoo has to male lions. one sixth of the lions are male lions.how many lions are there in the zoo?
Lesechka [4]
Well, this just shows how to divide fractions. (Not correct)

2 ÷ by 6 = 2 sixths   To solve you flip the reciprocal (6 over 1) to 1 over 6 then you multiply across.

2 x 1 = 2
_   _    _
1  x 6= 6             (flipped the 6 over 1 to 1 over 6 then multiplied across)
