Answer 1

Answer:

x=2;y= -4/3

Explanation:

4x+3y-4=0

4x+3y=4.........(1)

6x=8-5y

6x+5y=8.........(2)

multiplying eq.1 by 5 and eq.2 by 3

20x+15y=20.......….(3)

18x+15y=24............(4)

subtracting eq.3 by eq.4

2x=4

x=2

substituting x=2 in eq.1

4(2)+3y=4

8+3y=4

3y=4-8

3y= -4

y=-4/3
