4+((1−3x)/5)=−((x−5)/2)  Sir l could not solve this question  plz help me
$$\mathrm{4}+\frac{\mathrm{1}−\mathrm{3x}}{\mathrm{5}}=−\frac{\mathrm{x}−\mathrm{5}}{\mathrm{2}} \\ $$$$\mathrm{Sir}\:\mathrm{l}\:\mathrm{could}\:\mathrm{not}\:\mathrm{solve}\:\mathrm{this}\:\mathrm{question} \\ $$$$\mathrm{plz}\:\mathrm{help}\:\mathrm{me} \\ $$

4+(1/5)−(3/5)x=(−1/2)x+(5/2)  (−1/10)x=−17/10  x=17  S = {x∣x=17}
$$\mathrm{4}+\left(\mathrm{1}/\mathrm{5}\right)−\left(\mathrm{3}/\mathrm{5}\right){x}=\left(−\mathrm{1}/\mathrm{2}\right){x}+\left(\mathrm{5}/\mathrm{2}\right) \\ $$$$\left(−\mathrm{1}/\mathrm{10}\right){x}=−\mathrm{17}/\mathrm{10} \\ $$$${x}=\mathrm{17} \\ $$$$\mathbb{S}\:=\:\left\{{x}\mid{x}=\mathrm{17}\right\} \\ $$

    ((20)/5)+((1−3x)/5) = ((5−x)/2)            ((21−3x)/5)  =  ((5−x)/2)    2(21−3x)  =  5(5−x)            42−6x  =  25 −5x       −6x+5x  =  25−42                     −x  =  −17                          x  = 17
$$\:\:\:\:\frac{\mathrm{20}}{\mathrm{5}}+\frac{\mathrm{1}−\mathrm{3}{x}}{\mathrm{5}}\:=\:\frac{\mathrm{5}−{x}}{\mathrm{2}} \\ $$$$\:\:\:\:\:\:\:\:\:\:\frac{\mathrm{21}−\mathrm{3}{x}}{\mathrm{5}}\:\:=\:\:\frac{\mathrm{5}−{x}}{\mathrm{2}} \\ $$$$\:\:\mathrm{2}\left(\mathrm{21}−\mathrm{3}{x}\right)\:\:=\:\:\mathrm{5}\left(\mathrm{5}−{x}\right) \\ $$$$\:\:\:\:\:\:\:\:\:\:\mathrm{42}−\mathrm{6}{x}\:\:=\:\:\mathrm{25}\:−\mathrm{5}{x} \\ $$$$\:\:\:\:\:−\mathrm{6}{x}+\mathrm{5}{x}\:\:=\:\:\mathrm{25}−\mathrm{42} \\ $$$$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:−{x}\:\:=\:\:−\mathrm{17} \\ $$$$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:{x}\:\:=\:\mathrm{17} \\ $$
