\(\frac{x-1}{65}+\frac{x-3}{63}=\frac{x-5}{61}+\frac{x-7}{59}\)
\(\Rightarrow\frac{x-1}{61}-1\frac{x-3}{63}+-1=\frac{x-5}{61}-1+\frac{x-7}{59}-1\)
\(\Rightarrow\frac{x-66}{65}+\frac{x-66}{63}=\frac{x-66}{61}+\frac{x-66}{59}\)
\(\Rightarrow\left(x-66\right)\left(\frac{1}{65}+\frac{1}{63}-\frac{1}{61}-\frac{1}{59}\right)=0\)
\(\Rightarrow x=66\)
(x+1)/65+(x+3)/63=(x+5)/61+(x+7)/59
x+1/65+x+3/63=x+5/61+x+7/59
x+1/ 65 + x+3/ 63 = x+ 5/ 61 + x+7/ 59
x+1/65+x+3/63=x+5/61+x+7/59
x-1/65+x-1/63=x-5/61+x-7/59
