Answer 1

third option...
you'll have to work reverse order of operations

Answer 2

for questions like these you want to make x the subject so you wanna get constants on one side and x's on another side
so you will subtract the constant on both sides so... subtract 16 on both sides
this gives you 4x=4
divide by 4 to get x on its own
this gives x=1
