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)

(7−4x)/3=y...(2)

Put value of y in (1), we get

2x+3(7−4x)/3+1=0

2x+7−4x+1=0

x=4

from (2):

(7−4(4))/3=y

y=−3

Answer : x=4 and y=−3
