Pls help, i'll give you a brainliest 4 answer <3

babymother [125]

Answer:

$x = 45 \ \& \ y = 5$

Step-by-step explanation:

The system of linear equations in two variables is ,

$\begin{cases} x = 9y \cdots (i)\\ x - 5y = 20\cdots (ii) \end{cases}$

We can easily solve out this Question using substitution method . For that , substituting x = 9y from equation (i) to equation (ii) , we have ,

$\implies x - 5y = 20 \\\\\implies 9y - 5y = 20 \\\\\implies 4y = 20 \\\\\implies y =\dfrac{20}{4}\\\\\implies\boxed{\boxed{ y = 5 }}$

Substituting this value in (i) ,

$\implies x = 9y \\\\\implies x = 9\times 5 \\\\\implies \boxed{\boxed{ x = 45 }}$
