From figure, what is root of simultaneous equations
Answers
A value of each of the unknown or variable satisfies both the equation simultaneously. These values of the variables are the roots of the equations.
Given: A figure / graph showing two lines
2x-y = 2
x+ y = 4
To Find : root of simultaneous equations
Solution:
root of simultaneous equations is the intersection point of all the equation
2x-y = 2
x+ y = 4
Adding both
=> 3x = 6
=> x = 2
Substituing in
x + y = 4
=> 2 + y = 4
=> y = 2
Hence ( 2 , 2) is the root of simultaneous equations
From the graph intersection point of lines is (2 ,2 )
Hence root of simultaneous equations is ( 2 , 2)
