Answer 2

Answer:

The solution of the equation $2x+5y-3=0$ is $(-1,1)$.

Step-by-step explanation:

Given the equation $2x+5y-3=0$

Using the substitution method,  place the given set of $x,y$ values in the above equation, and check whether the result is zero or not.

If the result is zero, then that pair of values form the solution set of the given equation.

If $x=5, y=-2$ then

 $2\times5+5\times (-2)-3=10-10-3=-3\ne0$

If $x=-5, y=2$ then

$2\times(-5)+5\times2-3=-10+10-3=-3\ne0$

If $x=-1, y=1$ then  

$2\times(-1)+5\times 1-3=-2+5-3=0$

This pair of values form the solution set.

If $x=1, y=-1$ then

$2\times1+5\times (-1)-3=2-5-3=-6\ne0$

Therefore, the solution of the equation $2x+5y-3=0$ is $(-1,1)$.

So, the correct answer is option 3.
