in sufficent data to answer the question... if you mean what does x= when 2x= 319x-53 then... 2x+53=319x... 53=317x then x= (53 divided by 317)= 0.167192429, i tried my best with the awquad question, I'm sorry if that's not what you meant

When x equals 53 divided by 56
2x-15 = 53
53 squared equals 2,809.
53
1 x 53, 53 x 1
It equals 53.
53 is a prime, so 1 times 53 (unless you allow fractions).
-53 + 883 = 830
114-53=61
