Step-by-step explanation:

2x=7-4y

x=7-4y/2

4x+9-4=0

4(7-4y/2)+9-4=0

14-8y+5=0

8y=19

y=19/18

x=7-4(19/18)/2

Answer:

x=-5/4 ; y= 19/4 or 4.75

Step-by-step explanation:

By 1st equation we will find the value of x

4x+9-4=0

4x+5=0

4x= 0-5

4x = -5

x= -5/4

By the help of x we will find y

2×-5/4+4y=7

-5/2+4y=7

-5+4y=7×2

-5+4y=14

4y=14+5

4y= 19

y=19/4

y= 4.75
