Question

Match the equations of lines with their corresponding solutions.

• A. $(11,9)$
• B. $(6,3)$
• C. $(14,6)$

Answer 1

The solution of an equation must satisfy that equation.

Here,
$11+9=20\to (11,9)$ is a solution of $x+y=20$.

$2\times 6+3=15\to (6,3)$ is a solution of $2x+y=15$.

$14-6=8\to (14,6)$ is a solution of $x-y=8$.
