Question

write two equations of lines which are coincident with 2x+3y=9

Answer 1

Answer:

5y=9

1y+4y=9

maybe but if it's correct pls mark me as brainliest Hope it helps

Answer 2

Answer:

The equations of lines are: 4x+6y-18=0 and 6x+9y-27.

Step-by-step explanation:

Given: Equation of line is 2x+3y=9.

To determine two equation of coincident lines.

When two lines are coinciding to each other, then there could be no intercept difference between them.

i.e; lines $ax_{1} +by_{1}+c_{1}=0$ and $ax_{2} +by_{2}+c_{2}=0$ are coincident if:

$\frac{a_{1} }{a_{2} } =\frac{b_{1} }{b_{2} }=\frac{c_{1} }{c_{2} }$

Here $a_{1}=2, b_{1}=3,c_{1}=-9$

So, we can choose equation:

4x+6y-18=0 and 6x+9y-27.

As, 2/4=3/6=-9/-18 and 2/6=3/9=-9/-27

Therefore, the equation of coincident lines to 2x+3y=9 are 4x+6y-18=0 and 6x+9y-27.
