this is the answer

Answer 2

98x+102y=102

102x+98y=98

$\sf51(98x+102y)=102 \times 51 \\ \sf49(102x+98y)=98 \times 49$

$\: \: \cancel{4998x}+5202y=5202 \\ \cancel{4998x}+4802y=4802 \\ \hline \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 400y = 400$

y=1

4998x+5202×1=5202

4998x+5202=5202

4998x=0

x=0
