One of the most important and conceptual question from linear equations in two variables in which we have to find the value of variables x and y from the equations 2x+3y+1=0, (7-4x)/3=y

Kindly give me a detailed solution of this question

RS Aggarwal, Class 10, chapter 3B, question no 12

## 2x+3y+1=0...(1)

(7âˆ’4x)â€‹/3=y...(2)

Put value ofÂ yÂ inÂ (1), we get

2x+3(7âˆ’4xâ€‹)/3+1=0

2x+7âˆ’4x+1=0

x=4

fromÂ (2):

(7âˆ’4(4))/3=y

y=âˆ’3

Answer :Â x=4Â andÂ y=âˆ’3
