Question
Write two solutions for the following equations: $\text{x}+\pi\text{y} = 4 $
✓
Answer
We are given, $\text{x}+\pi\text{y} = 4 $
Substituting $x = 0$ in the given equation,
we get $\text{x}+\pi\text{y} = 4 $ $\pi\text{y}=4-0$
$\text{y}=\frac{4}{\pi}$Thus $x = 0$ and $\text{y}=\frac{4}{\pi}$ is the solution of $\text{x}+\pi\text{y} = 4 $
Substituting $x = 6$ in the given equation,
we get $\text{x}+\pi\text{y} = 4 $
$\pi\text{y}=4-0$
$\text{y}=\frac{0}{\pi}$ $\text{y}=0$
Thus $x = 4$ and $y = 0$ is the solution of $\text{x}+\pi\text{y} = 4 $
