Question

which of the following is a solution of equations 2x-3y=5?
a. (-2,-3)
b. (4,6)​

Answer 1

Answer:

Given equations are 2x+3y−5=0 and 4x+ky−10=0

Then 2x+3y−5=0⇒2x+3y=5

4x+ky−10⇒4x+ky=10

∴   2/4  =  3/k =  5/10 .... [Since, they have an infinite number of solutions]

⇒  1/2  =  3/k  =  1/2

⇒  1/2 =  3/k

⇒k=6

hope it is helpful

Answer 2

Answer:

the equation is 2x-3y=5

Step-by-step explanation:

Lets take option a.

(-2,-3)

Here -2 is the x-coordinate and -3 is the y-coordinate.

Therefore substitute -2 for x and -3 for y.

2(-2) - 3(-3)=5

i.e. -4=9=5

5=5
