x-1/2020+x/2016+1/502 = x-3/2012+x/2008+1/1008 =>x + x/ 2016 − 1/ 2020 + 1/ 502 = x − 3/ 2012 + x/ 2008 + 1/ 1008 =>x/ 1 + x/ 2016 − 1/ 2020 + 1/ 502 = x − 3/ 2012 + x/ 2008 + 1/ 1008 =>(2020x-1)/2020 + x/ 2016 + 1/ 502 = x − 3/ 2012 + x/ 2008 + 1/ 1008 =>(507020x+759)/507020 + x/ 2016 = (507024x-253)/507024 +x/2008 =>253512 ( 507020 x + 759 ) + 63757765 x = 128599666020 x − 64138030 =>128599412005 x − 128599666020 x = − 64138030 − 192415608 =>− 254015 x = − 64138030 − 192415608 =>254015 x = 256553638 =>x=256553638/ 254015 Vậy x=256553638/ 254015 Trả lời
Giải đáp:x-1/2020+x/2016+1/502 = x-3/2012+x/2008+1/1008=> (x-2020+2019)/2020 + x/2016 + 1/502 = (x-2012 + 2019)/2012 + x/2008 +1/1008=> (x+2019)/2020 – (x+2019)/2012 +x/2016 – 1/1008 +1/502 – x/2008 = 0 => (x+2019)/(1/2020 – 1/2012) + (x-2)/2018 + ( 4-x)/2008 = 0 Trả lời
=> (x-2020+2019)/2020 + x/2016 + 1/502 = (x-2012 + 2019)/2012 + x/2008 +1/1008
=> (x+2019)/2020 – (x+2019)/2012 +x/2016 – 1/1008 +1/502 – x/2008 = 0
=> (x+2019)/(1/2020 – 1/2012) + (x-2)/2018 + ( 4-x)/2008 = 0
