Please help I don't know how to do this

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

you just switch the numbers basically so it would be 3/17

the answer to 1/4x+5/3x-4=2-1/12x is x=3

hope this if needed hmu
