$\huge\boxed{\fcolorbox{red}{blue}{ QUESTION }}$

x + 5y = 28

2x + 3y = 21

Solve for x and y

$\huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}$

$(x + 5y = 28).... \times 2 \\ \\ 2x + 3y = 21 \\ \\ 2x + 10y = 56 \\ \\ sub...both \: eq.. \\ \\ - 7y = - 35 \\ 7y = 35 \\ y = 5 \: \: \: \: ans \: \: \\ \\ put \: y \: in \: eq \:( 1) \\ \\ x + 5y = 28 \\ x + 5(5) = 28 \\ x + 25 = 28 \\ x = 3 \: \: \: \: ans \:$
