Solve the following pair of linear equations by substitution method.
(i) \( x-y=2,3 x+2 y=16 \)
(ii) \( 7 x-4 y=3, x+2 y=3 \)
(iii) \( 3 x+7 y=37,5 x+6 y=39 \)
(iv) \( \frac{3 x-4 y}{2}=10, \frac{3 x+2 y}{4}=2 \)
(v) \( y=\frac{2}{3} x+6,2 y-4 x=20 \)
(vi) \( 3 x-\frac{y+7}{11}=8,2 y+\frac{x+11}{7}=10 \)
(vii) \( 1.1 x+1.5 y+2.3=0,0.7 x-0.2 y=2 \)
(viii) \( 0.2 x+0.3 y=1.3,0.4 x+0.5 y=2.3 \)
(ix) \( \sqrt{7} x+\sqrt{11} y=0, \sqrt{3} x-\sqrt{5} y=0 \)
(x) \( 7(y+3)-2(x+2)=14,4(y-2)+3(x-3)=2 \)
