Question

Write any one solution of equation $x+2y=7$.

Answer 1

For any solution we will put a value of $y$ and by solving we will find the corresponding value of $x$.

This is a straight line and has infinite number of solutions.

For example,

$y=1$

$x=$$7-2\left(1\right)$ $=5$

Hence, $(5,1)$ is one of the solution of the given equation.
