6 X + 5 + y by 3 is equal to 2.3 equation 1

X by 10 - 2 y by 3 is equal to 1.2 equation 2

6 x 5 + y by 15 is equal to 2.3 = to 18 x + Y is equal to 34.5 eq1i

by taking LCM

equation 2= 3 X - 20 Y =36 equation 2i

by taking LCM

18 x + Y =34.5

18 x _1200 Y =+ 216

_ + -

121y =181.5

substitute Y as 1.3 in equation 1 I

18 x + 1.3 is equal to 34.5

18 x = 35.8

x = 1.9

therefore Y is 1.3 and X is 1. 9
