Question

2 B Solve.
(1) Identify and write the linear equations in two vari
following
x + 2x + y = 0 ; x + y + 5 = 0 : 2x - 3y = 5:
3y = 9x - 2 ; m + mn + 2 = 0 : 3 = 3m + 2n​

Answer 1

Answer:

all equation are two variable

x+2x+y=o

3x+y=0 ,. x+y+5=0,2x-3y=5,

3y=9x-2

9x-3y=2,

3=3m+2n.

3m+2n=3.

only 2m+mn+2=0

is not two variable equation
