Question

What are the possible solutions for the equation $x+2y=10$?

• A. $x=0$ and $y=5$
• B. $x=10$ and $y=0$
• C. $x=5$ and $y=5$
• D. $x=4$ and $y=3$

Answer 1

Answer: (A), (B), (D)

The correct options are
A $x=0$ and $y=5$
B $x=10$ and $y=0$
D $x=4$ and $y=3$

Given that,
equation is $x+2y=10$.

Now,
checking for every option.

Putting $x=0$ and $y=5$ in the equation,
we get 10 = 10.

Putting $x=10$ and $y=0$ in the equation,
we get 10 = 10.

Putting $x=5$ and $y=5$ in the equation,
we get 15 which is not equal to 10.

Putting $x=4$ and $y=3$ in the equation,
we get 10 = 10.
