Question

3. Write a solution of the equation 2x + 3y = -6​

Answer 1

Answer:

sorry but I think this is wrong

Answer 2

Answer:

The general form for a pair of linear equations in two variables x and y is

a

1

x+b

1

y+c

1

=0 and

a

2

x+b

2

y+c

2

=0

2x−y=1 ----- (1)

2x+3y=3----- (2)

Comparing equations 1 and 2 with the general form of equation to write their co-efficient,

a1=2;a2=2;b1=−1;b2=3;c1=1;c2=3

Compare the ratio,

a

If

a



=

b

, then the pair of linear equations has exactly one solution.

So,
