Question

Find three solution for linear equation in two variables 3x + y =7

Answer 1

here is your answer

Answer 2

Substitute any value of x, we will get value of y.

Let x = 1/3 .
Now, 3x + y = 7
=>3(1/3)+y = 7
=> y = 6 .

Let y = 0 .
Now, 3x + y = 7
3x = 7
x = 7/3 .

Let x =2 .
Now, 3x + y = 7 .
3(2)+y = 7 .
y = 1 .

Solutions of 3x+y=7 :- (1/3,6) , ( 7/3,0) , ( 2 , 1 )
