Question

7-4x/3=y
, 2x + 3y + 1 = 0
​

Answer 1

Answer:

x=11,y=-23/3

Step-by-step explanation:

21-4x=3y

4x+3y=21--(1)

2x+3y=-1--(2)

(1)-(2)

2x=22

x=11

44+3y=21

3y= -23

y= -23/3

Answer 2

Step-by-step explanation:

2x+3(7-4x/3)=0

2x+3(21-4x/3)+1=0

2x+21-4x+1=0

-2x+20=0

-2x=-20

x=10

then,2x+3y+1=0

2(10)+3y+1=0

20+3y+1=0

21+3y=0

3y=-21

y=-7

then,

x=10,y=-7
