Question

Write any two solutions of the equation $x+y=7$

Answer 1

Determine two solutions of the equation $x+y=7$:

Any pair of $\left(x,y\right)$ that satisfies the equation $x+y=7$ is the solution of the given equation.

Now, let $x=0$, then

$$\begin{gathered} \Rightarrow 0+y=7 \\ \Rightarrow y=7 \end{gathered}$$

Put $x=1$ then,

$\begin{array}{rcl}1+y& =& 7\\ & \Rightarrow & y=7-1\\ \therefore y& =& 6\end{array}$

Thus, $\left(0,7\right)$ and $\left(1,6\right)$ are the two solutions of the equation $x+y=7$.
