Hey Dude good afternoon ❤️❤️

Here is your answer ✌️✌️✌️

4X + Y/3 = 8/3

multiply each term with 3 , we get

12 X + Y = 8

= Y = 8 - 12X ......... (1)

X/2 + 3Y/4 = - 5/2. ........ (2)

Substitute Y = 8 - 12X in equation ( 2 ),

X/2 + ( 3/4 ) [ 8 - 12x ] = - 5/2

= X/2 + 3 [ 8/4 - 12X/4 ] = - 5/2

= X/2 + 3 ( 2 - 3X ) = - 5/2

multiply each term with 2 , we get

= X + 6( 2 - 3X ) = - 5

= X + 12 - 18X = - 5

= - 17X = - 5 - 12

= - 17 X = - 17

= X = ( -17 )/( -17 )

X = 1

put X = 1 , in equation ( 1 ) , we get

Y = 8 - 12 × 1

Y = 8 - 12

Y = - 4

Therefore ,

x = 1 , y = - 4
