Answer 2

answer

3h + 4k = 13---------( i )

4h - 3k = 19----------( ii )

(i) x 4=> 12h + 16k = 52

(ii) x 3 => 12h + 9k = 60

_____________________________

(-). 7k = - 8

k = -8/7

(ii)= 12h + 72/7 = 60

$\binom{84 + 72}{7} = 60$

84h + 72 = 60 x 7

84h = 420 - 72

h =

$\frac{384}{84}$

= 32/7

therefore k = -8/7 & h = 32/7
