49/9 + x - 63/8 = 63/4
x - 63/8 = 63/4 - 49/9
x - 63/8 = 371/36
x = 371/36 + 63/8
x = 1309/72
49/9+x =63/4+63/8
49/9+x =189/8
x =189/8+49/9

\(\frac{49}{9}+x-\frac{63}{8}=\frac{63}{4}\)
\(\frac{49}{9}+x=\frac{63}{4}+\frac{63}{8}\)
\(\frac{49}{9}+x=\frac{189}{8}\)
\(x=\frac{189}{8}-\frac{49}{9}\)
\(x=\frac{1309}{72}\)
