Step-by-step explanation:

\Huge\tt\underline\red{Answer}

39x+43y= 203

=> 39x= 203-43y

=> x= 203-43y/39. ----> (i)

Now putting (i) in 43x+39y= 207 we have

43(203-43y)/39+39y= 207

=> 43*203-43*43y/39+39y= 207

=> 43(200+3)- 1849y+ 39*39y/39= 207

=> 8600+129-1849y+ 39(40-1)y= (200+7)39

=> 8729-1849y+1560y-39y= 7800+273

=> 8729-(1849-1560)y-39y= 8073

=> 8729- 289y-39y= 8073

=> -(289+39)y= 8073-8729

=> -328y= -656

=> y= -656/-328

=>y = 2

x= 203-43(2)/39

= 203-86/39

= 117/39

hope it helps
