We first have to distribute the outside 2. That means we have to multiply the numbers in the parentheses by the outside 2.
2*2y is 4y and 2*16 is 32.
So now we have 4y-32=0
Now we have to combine like terms, basically.
So we do inverse operation, the opposite operation. So let's add 32 to the 0. That's obviously 32.
So 4y=32. We do inverse operation again. So we divide 32/4. We get 8.
And 8 is our answer. 8=y
Hope I helped :)
