Answer:
for level 1: x=36
because you just need to do 180-144
for level 2: x = 127
you can just so 180-15-38
for level 3: x = 36
because you start by setting an equation like this:
92 + (2x+16) = 180
subtract 92 from both sides, then subtract 16 from both sides, and finally divide both sides by 2 to get 36
