Question
Write two solutions for the following equations: $\frac{2}{3}\text{x} - \text{y} = 4$
✓
Answer
We are given,$\frac{2}{3}\text{x} - \text{y} = 4$
Substituting $x= 0$ in the given equation, we get
$\frac{2}{3}\text{x} - \text{y} = 4$
$0 - y = 4$
$y = -4$
Thus $x = 0$ and $y = -4$ is the solution of $\frac{2}{3}\text{x} - \text{y} = 4$
Substituting $x = 6$ in the given equation, we get
$\frac{2}{3}\text{x} - \text{y} = 4$
$-y = 4 - 2$
$y = -2$
Thus $x = 3$ and $y = -2$ is the solution of $\frac{2}{3}\text{x} - \text{y} = 4$
