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
