Answer:
Physics formulas, chemical structures, chemical conversions and reactions. ... solve y' = y^2 x ... prove by induction sum of j from 1 to n = n(n+1)/2 for n>0.
Step-by-step explanation:
x=18
12-2/3x=x-18
12-2/3x-x=-18
12-2/3x-3/3x=-18
12-5/3x=-18
5/3x=12-(-18)
5/3x=12+18
5/3x=30
x=30/(5/3)
x=(30/1)(3/5)
x=90/5
