Iam confused on this question because i keep getting different answers . 6 ÷ 2(1 + 2)

This is a pemdas problem. The basic rule of pemdas is:

Multiplication/division and addition/subtraction are in no particular order; they are solved from left to right.

Since you solve inside the parentheses first, you would first add 1 and 2 together and then rewrite the problem.

6 ÷ 2(3)

Now you have 6 divided by 2 multiplied by 3. Pemdas shows that division and multiplication are solved in no particular order, so that means that you will solve this expression from left to right.

Start by dividing 6 and 2, then rewrite the problem.

3(3) is what you are left with.

Multiply 3 and 3 together and you will be left with your final answer of:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
