Question

find three solution of 3x+y =6​

Answer 1

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

3x+y=6 ----- (1)

6x+2y=3----- (2)

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

a1=3;a2=6;b1=1;b2=2;c1=6;c2=3

Compare the ratio,

Answer 2

Answer:

3 x 1 + 3 = 6

3x2+0= 6

3x3 + (-3) = 6
