Question

Identify and write the linear equations in two variables from the
following
x + 2x + y = x + y + 5 = 0; 2x – 3y = 5;
3y = 9x - 2 ; m² + mn + 2 = 0 ; 3 = 3m + 2n​

Answer 1

Answer:

2x , + 5 are the two variables

5 , 2 are the two variables

2 ,0 are the two variables

m , n are the two variables

Answer 2

Answer:

2x-3y=5

3y=9x-2

3=3m+2n

Step-by-step explanation:

1)In this x&y are the only variables and the highest index of variable is 1 . Therefore it is a linear equation.

2)3y-9x=-2 is also linear equation because x&y are the only variables and it degree is 1.

3)3m+2n = 3 is a linear equation because x& y are the only variables and its highest degree is 1.
