73(21.9-x)=51(21.9-y) x=35y/73

Question

73(21.9-x)=51(21.9-y) x=35y/73

Answer 1

{73(21,9-х)=51(21,9-у)
{х=35у/73

73 (21.9 -  35y/73)= 51*21.9- 51y
73*21.9  -  35y  =  51*21.9-51y
-35y+51y = 51*21.9  -73 *21.9
16y= 21.9*(51-73)
16y = 21.9 *(-22)
y= -481.8/16 = -4818/160 =-30  18/160 = -30  9/80
y= -30.1125

x= (35*(-30.1125) )/73 = - 1053.9375 / 73
x=-14.4375
