Answer 2

Step-by-step explanation:

$\huge \mathcal \red{A}\huge \mathcal \green{n} \huge \mathcal \orange{S}\huge \mathcal \blue{w}\huge \mathcal{E}\huge \mathcal \green{r - }$

Substitution Method -

$x + 3y = 8 \\ 2x - 9 = y \\ \\ \bold{putting \: the \: value \: of \: y \: on} \\ \bold{x + 3y = 8} \\ \\ x + 3 \bold{(2x - 9)} = 8 \\ \\ x + 6x - 27 = 8 \\ \\ 7x = 35 \\ \\ x = \frac{35}{7} \\ \\ x = \bold{5} \\ \\ \bold{now , \: putting \: the \: value \: of \: x = 5 \: on} \\ \bold{2x - 9 = y} \\ \\ 2 \bold{(5)} - 9 = y \\ \\ 10 - 9 = y \\ \\ y = \bold{1}$
