Question

solv for x and y using elimination method 2x+3y+1=0 , 7-4x/3=y​

Answer 1

Answer:

x=4 and y=-3

Step-by-step explanation:

2x+3y+1=0

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

7-4x/3=y

7-4x=3y

4x+3y=7-----------2

subtract equation 1 from 2

4x+3y=7

- 2x+3y=-1

2x=8

x= 8

2

x=4

taking x=4 in equation 1

2×4+3y=-1

8+3y=-1

3y=-1-8

3y=-9

y=-9

3

y=-3

Answer 2

Answer:

4

Step-by-step explanation:

7-4x/3=y

7-4x=3y _____(1)

from (1)

2x+(7-4x)+1=0

2x+7-4x+1=0

-2x+8=0

-2x=0-8

-2x=-8

X=-8/-2

X=8/2

X=4

Therefore, X=4
